Summary: Kernel crashes aprox. every 36 hours.
Description: Machine locks up, or crashes way to often. The latest crash
produced log output that hinted at the problem, but I don't know
how to interpret what I'm seeing.
The crashes can be quite severe. The previous one wiped out my /usr
partition.
Keywords: Machine exception, hang, crash.
Kernel Version: Linux version 2.4.29 (root@morningstar)
(gcc version 2.95.4 20011002 (Debian prerelease))
#4 SMP Mon Mar 28 18:29:11 MST 2005
Oops: None. Usually, the machine simply hangs and has to be power
cycled. The latest crash gave me a few lines in the log:
May 27 21:42:06 morningstar kernel: CPU 1: Machine Check Exception: 0000000000000004

Often symptoms of flaky hardware, insufficiently cooled CPU or defective RAM.

Disk corruption may be caused by one of the troubles above. However, you
should not have lost everything, usually, playing long with fsck allows
you to retrieve most of your data.

This is the most important part. You must pass to to "parsemce" which will
tell you what's wrong. You can find it on codemonkey.org.uk (google will
direct you to the right site).

You have a dual-athlon MB, I too have one (ASUS A7M266D), and encountered
stability problems during last summer because the temperature was getting
high in the case when I slowed down my fans to keep them quiet. The RAM
can get very hot too. Perhaps one of your fans does not spin fast enough
because of dust ? You may have a problem with the power supply too, since
those CPUs suck a lot of power. Anyway, your report clearly is a problem
with hardware, I would advice to make a lot of backups.
Regards,
Willy

That's a timeout on a L1 data cache evict, probably related to the
following:

That's an uncorrectable (multibit) ECC error on a L2 cache read.
I would look for BIOS updates or replace the RAM. You should probably
see failures if you run memtest86 also.
