I've played with the PCI settings - and that WAS part of the problem, initially - playing with them is what got Debian to boot at all. Right now, I think it is marginal HW that's screwing me up. This box is built from parts of old dead PCs - it's my 'Frankenbox Monster' - heck the HDDs were scavenged from a dumpster here in my apt. complex! The memory was mostly bought (128m), but the last 64mb came from dead machines here in my apt. The video (the Trident Cyberblade / 32m) was also purchased, because I could pick it up for $30 at a PC trade show that a buddy took me to. The 3c509 card is many years old - it used to run in 'Max', my old server - but it gave me problems there intil I replaced it with a generic PCI card a year ago. Replacing an IDE cable has bought me a little more reliability, it seems - now I can 'reliably' do a Debian net install of the base system, at least.

Post #66,130 by rickmoen 12/2/02 1:20:46 PM Reply	Looks to be bad hardware Well, you know, if my machine did that, I'd immediately think bad hardware. The primary candidates would be the RAM and the hard-drive host adapter, in that order. If there's a possibility of heat build-up, that would also be worth checking. (Check for overall heat build-up, jammed or blocked fans, slipped heat-sinks.) Also, on a theory that you might be trying to push some hardware component past spec, go into your BIOS Setup program, and revert its state to factory defaults (because those are the most conservative and least aggressive). My first step actually would be to burn an LNX-BBC disk, or in any other way acquire bootable media capable of running memtest86, which I would then run overnight. RAM that passes an overnight run of memtest86 can be pretty much ruled out as a suspect. Sometimes, people I tell this to will resist, saying "But I've installed operating system Foo a dozen times, with no problem." However, either the hardware glitch has arisen since your last installation, or Foo is oblivious to most hardware faults, or both. For example, all Microsoft OSes' installers of my acquaintance will blithely ignore severe memory errors and cheerfully create configurations that will then slowly and silently autocorrupt on account of data passing through the bad RAM patch thereafter. NetWare and OS/2 are significantly better. FreeBSD and Linux show signs of distress that are immediate and unmistakeable, if you're familiar with them. For non-RAM hardware errors (such as screwy ATA chipsets), FreeBSD and Linux are sometimes a bit more opaque in the clarity of their complaints, but they'll definitely let you know something is wrong. And that's precisely what your situation sounds like. Rick Moen rick@linuxmafia.com If you lived here, you'd be $HOME already.

I honestly hadn't noticed that he said this was a laptop. In the case of laptops, you can indeed have special problems: I tend to almost unconsciously disable power management on them, and avoid using funny stuff that can complicate diagnosis (lm-sensors, apmd, tweaked non-conservative ATA driver settings, etc.). Anyone who's playing with such things should (obviously) switch them off as a necessary initial diagnostic step. I'm not sure what your point is about laptops' Power-On Self-Tests. They should not be relevant subsequent to boot-up. I urge placing scant-to-no reliance on any assurance they might purport to give about one's hardware being healthy. In my experience, their alleged hardware-OK results are nearly meaningless, particularly as to RAM, but also in other areas. As for memtest86, don't know how that is put together but it fails on my Toshiba Tecra 8000 with 256M (not 128M), while Windows 2000 runs fine there. I'll guess that Windows is more conservative about timing issues. If my RAM failed the current memtest86 version, and wasn't some extremely new type of RAM on some very new motherboard chipset, I would be strongly inclined to believe it defective. I have seen various NT versions pose no objections to RAM that turned out later to be proveably defective. I would be especially cautious on this matter given the dropping of parity support from practically all x86 machines, following the example of Intel's Triton series motherboard chipsets, some years back. Again, the reason to be cautious is that undetected bad RAM can and does lead to gradual, progressive, and silent corruption of data that happens to pass through it. On the other hand, if some assurance about hardware quality from MS-Windows 2000 strikes you as good enough to bank on, then I hope your trust is justified, and wish you the best of luck.

Depending on what you mean by "fried", this might point to the underlying cause. Back a number of years ago, we were having a several-day heat wave in San Francisco, reaching about 40 Celsius (maybe 103 F). That day, I was in my apartment, stripped to my waist, and made the judgement error of trying to reload my 486 tower with OS/2 3.0 from CD media, with the case open (and thus no proper forced-air flow). Furthermore, I'd made the error of mounting one of the system's two fast SCSI drives mounted with only about 5 mm of air space between the drive's electronics and a blocking steel bracket. As a result, the drive's electronics partially cooked, and some data writes thereafter were not reliably correct. Everything seemed OK at the software level: CRC values got calculated and confirmed, but in some cases the CRCs were generated and stored (accurately) on the basis of already incorrect datastreams. I didn't figure out what had happened for a few days, and could confirm it only indirectly after swapping out the drive. Anyhow, my point is that if there has been a past heat episode in the machine we're talking about, you need to consider the possibility that more damage occurred at that time, not just the drive that got "fried", then. There may have been heat stress to other components, or electrical damage. (People are sometimes surprised when they ask me "May I test this board I think is bad on your motherboard?" and I reply "No!" Somehow "Oops, I'm sorry" doesn't suffice when someone damages my motherboard.) If it eventually comes down to "Some hardware is acting up, I'm not sure which, and I've ruled out software/firmware configuration", then I guess you'll be spending a fun time honing your hardware diagnostic skills: You can try removing non-essential hardware, to see if they problem goes away. You can test suspect equipment a piece at a time in a different system that's known-good. You can swap in temporary replacements for suspect components in the suspect machine. There are no doubt other basic approaches that aren't readily coming to mind, but those are some of the classics. Rick Moen rick@linuxmafia.com If you lived here, you'd be $HOME already.

Post #66,295 by deSitter 12/2/02 11:00:59 PM Reply	Smoke Emitting FPUs I had an easy diagnosis once. I learned UNIX from a guru, and he put me, his one and only student, in charge of the engineering development machine for a Star Wars project. Well, the Main Programmer was a PhD in math - so he hated physicists. He'd always look at me in the lab as if to say - "Physicists! Bah!" But root was the brains of the operation. Root was so called because he was ugly as sin but had a beautiful lady on his arm all the time, and drove a purple Cadillac. I drove a red Mustang 5-liter convertible. He was good at ballroom dancing. I wasn't. (But I did OK too :) Anyway for the development system root put me in charge of - one day the long sought-after external FPU for the 68030 (68882?) arrived, and root bid me install it in my own system! Well, Mr. math PhD would not hear of it! He insisted on installing it himself! Well, he installed it sideways (it was square) and that was not good. The very expensive FPU was destroyed, but the rest of the system lived on and accepted a new FPU a week later, installed by me. I never talked much to Mr. Math PhD after that. He said my C programming looked like FORTRAN - and he was right. He wouldn't admit it, but he was impressed with my VAX FORTRAN parser written in XEDIT on an IBM 4341 running VM/CMS. Pretty soon Star Wars ended, and Business by Numbers began, and then it was now. -drl
Post #66,336 by rickmoen 12/3/02 1:18:05 AM 12/3/02 4:18:55 PM Reply	Re: Smoke Emitting FPUs Good story there. Thanks. I did a bonehead manoeuver, once, at the time I bought my K6/233 motherboard. Not as bad as your math Ph.D colleague's, and more cheaply recoverable, but funny. This was back when you paid only a small premium for building up from individual components of your choosing: The price gap has widened since then. I was trying to put together a system from quality, maximum-bang-for-buck components, and so got an FIC PA-2007 mini-AT-format mainboard, K6/233, a separate huge CPU heat sink with ball-bearing fan, big tower case, PC Power & Cooling TurboCool PSU, an Adaptec AHA-2940UW, Number Nine Imagine 128 video, and 64 MB Corsair SDRAM (augmented later on, but only 64 MB initially) rated for CAS2 operation at 100MHz on the local memory bus. Carried forward from older boxen were an old Keytronics motherboard, Logitech Trackman Marble, a pair of 10k RPM IBM wide-SCSI hard drives, an old Toshiba ATAPI CD-ROM, a Toshiba floppy, and a pair of antique 3Com 3C509 ethernet cards. I banged the machine together, flipped it on, loaded Debian, and started trying to use it. SIG11 errors started cropping up. Hmm, that's odd. Power it down, check for sources of heat problems, spaced out the cards and hard drives, made sure all fans were working, made sure there was no air blockage. Took a coping saw and made a cutout on the drive bracket, and mounted another muffin fan pointing upwards at the hard drives through it, just for an additional safety factor. Made sure nothing was jamming the CPU or power supply fans. Put the beast back together, powered up: No problems. Good. Half hour later, a consistent string of SIG11s, especially if I started doing strenuous things like kernel compiles. Damn. Open 'er up again. Recheck for heat concentrations: None. Everything seems to be running cool. OK, am I seeing a sensitive CPU, dodgy RAM, or what? Run memtest86, no problems. Hmm. I'm being tempted, at this point, to try exchanging the CPU. But I want to try one thing out: I check out where the heat sink was mounted onto the CPU: I had a sort of heat-transferring pad between them, that came with the heat sink. So, I go down to Fry's Electronics, and buy some more of that stuff, and also a tube of heat-conducting paste, which one can use instead, in such places. Get back to my machine, take the heat sink off. Try a freshly cut piece of conductive pad. Basically the same results, except a pattern is starting to emerge: I can do the heaviest number-crunching I like within the first 20-30 minutes from power-on, without trouble. Afterwards, anything even mildly strenuous (e.g., kernel compiles) will generate Signal 11 errors. Conclusion: Something is heating up, 1/2 hour from power-on. It's not a strictly operational thing, but rather heat build-up over time. I shut down, and take the CPU heat sink off, again. Pull the pad out, and clean all surfaces. Put the heat-conducting paste onto the bottom of the heat sink, latch it onto the CPU. Lock everything back in place, re-test. Same results. Hmm, dodgy CPU? Shortly before I jump to that (wrong) conclusion, I pull the heat sink off, again. I put the heat sink upside-down on my desk and stare at it. Oh, fsck. What a dumbass error. The outline of the K6 is square, as is its socket. The heat sink is also square. Unlike your Ph.D friend's FPU, the K6's socket is keyed to admit it in only one orientation, so you cannot fry it that way. So, you think, square CPU that can be inserted only the correct way; square heat sink that goes on top; lever that locks the heat sink down. Put heat sink A on chip B in socket C; what can go wrong? There are two orientations the heat sink can mount onto the CPU; 180 degree rotations of one another. Both must be right, right? Wrong. The contact area on top of the CPU is offset towards one side, and is maybe 65% of the total square. The bottom surface of the heat sink projects downwards only on the lateral side only where the matching 65% of its contact surface can touch the CPU's contact area below it. You can verify that this has happened if/when you yank the heat sink and newly-squeezed thermal paste, because the thermal paste will be mashed from contact with the CPU. Likewise, the CPU's contact area will have some detached thermal paste smeared across it. Only mine wasn't. On the heat sink bottom, only the paste near the centre of its contact area was mashed, with the remainder dangling into space exactly the way I'd dabbed it on. The CPU's upper surface sported only a little paste, near the middle: Most of the CPU's contact surface had been air-gapped, rather than heat-sinked. Luckily, trapped heat across most of the CPU had not turned it into silicon carne, and everything worked beautifully once I flipped the friggin' heat sink around the correct way. The silver lining is that that machine emerged from the exercise with awesomely efficient cooling. Rick Moen rick@linuxmafia.com If you lived here, you'd be $HOME already.

TRAP0002, which was a rather opaquely worded software-level report of NMI (non-maskable interrupt) problems at the underlying hardware level. Damn, that's starting to come back to me. You generally got slightly more immediate, slightly more strident, and slightly easier-to-interpret memory-fault error reporting from the Linux kernel (not that "Signal 11" and "Segmentation Fault" is exactly crystal-clear, either), but OS/2 was/is pretty good at that.

And at that point Linux certainly wasn't being used in "real businesses", let alone a big 6 CPA firm... ;-) Which suggests a topic for a new thread...
