random reboots

Help!

My machine seems to be rebooting at random. Actually, it's more like the screen blanks, and suddenly the BIOS is going through POST. There may be a reset-button gnome in my case putting a jumper over the reset pins, but I seriously doubt it. ;-) I recently tried to switch from APM to ACPI, when i upgraded from ac9 to ac11, so I thought that might be the cause. So I switched back to APM with ac13 (I had the same ac12 compile problems as the rest of the world). It's still rebooting, without any aparent cause.

I upgraded the BIOS on this Asus A7V sometime in the past week, but I honestly don't remember when. From 1005C to 1007. This was released in march, so I assumed it was pretty stable, but it could be the cause. I'm going to go downgrade now, but is this more likely to be a kernel bug, or a hardware bug/new bios bug?

Thanks,
Nathan

No problem here. I'm using 1007 since its release in first half of March.

Linux version 2.4.3-ac12-amd (root@ppc) (gcc version 3.0 20010402 (Debian prerelease)) #1 Mon Apr 23 02:31:13 CEST 2001
...
Kernel command line: BOOT_IMAGE=Linux ro root=2105 video=matrox:vesa:0x105,fv:85 devfs=nomount Initializing CPU#0
Detected 1009.013 MHz processor.

CPU: AMD Athlon(tm) Processor stepping 02
Enabling fast FPU save and restore... done.
...
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.14)

Except that I got 'ide only func: 14' today with my Promise PDC20265 (which looks strange to me - either all Intel, VIA and Promise have same bug in their UDMA hardware, or there is a bug in Linux IDE driver...) (I had to reboot because of kernel somehow believed that it read some garbage instead of MBR from hdg, so I could not run my repartitioning session, as I found no way to invalidate hdg kernel cache).
But machine for sure does not spontaneously reboot. And I have enabled local apic in kernel configuration. All previous kernels were built with Debian's 2.95.3-something, ac12 was built with gcc-3.0, as I wanted to update anyway, and ac12 just gave me a reason.

I've gotten a lot more response to this than I'd ever dreamed, but I figured out the problem on my own...

I have (had) one of those exhaust fans that fits into a PCI/ISA slot, and it died. Not only did it die, but it started creating heat of it's own. I don't think the video card adjacent to it appreciated this a whole lot. I removed the dead fan, and everything is back to normal, I just need to go get a new fan to make myself feel better ;-)

The 1007 bios, and ac14 have been perfectly stable, so no worries about either.

Thanks,
Nathan
