Red Hat Bugzilla – Bug 5474
frequent kernel crash
Last modified: 2008-05-01 11:37:51 EDT
Ever since RH 6.0, I've been having a lot of problems with
crashing kernels. I've upgraded the kernel-related packages
to 2.2.5-22 and the XFree86 packages to 3.3.5-1.6.0.
Usually, the crash is either associated with opening lots of
windows (swapping problem, bug 4224), netscape (X font
server, bug 4187) or just simply leaving the computer
running for several days. Usually, the crash occurs when I
shut down the X-server, log out (as an ordinary user in run
level 5) or changing to run level 1. There is so much
diagnostic and the computer hangs, requiring a hard reboot.
(Occasionally, as a result, some packages get corrupted and
I have to reinstall them.) A few days ago, the diagnostic
was short enough to fit on the screen, so I was able to
transcribe them before rebooting. Here goes:
Output left on the last screen before the computer hung.

At this point, the computer hung.
At other times, diagnostics claims a kernel panic. Yet
other times, there is no diagnostic at all--it just hangs.
I realize that this is not very specific information. Let
me know how to get more better information on the crash.
One thing you can do is run the oops through the
'ksymoops' program (it's included in the kernel source
in /usr/src/linux/scripts/ksymoops). This will show exactly
where the kernel dies at.

Please download and install the 2.2.12-20 kernel from the Red Hat
Linux 6.1 distribution and see if the problem continues. Report that
back here. Until we know if the problem still happens this bug report
will be on hold.

Where is the Oops file located?
I've updated to kernel 2.2.12-20--The problem still exists.
The problem description you've given so far sounds largely like a hardware
corruption issue. We have a standard test we run on systems to see if there are
hardware problems. That test requires about 100MBytes of free disk space, one
of the linux-2.2.x.tar.gz kernel source tar balls, and the following script:
rm -fr linux linux.save
tar xzf linux-2.2.0.tar.gz
mv linux linux.save
while [ "$i" -lt "10" ]; do
tar xzf linux-2.2.0.tar.gz
diff -U 3 -rN linux.save linux
rm -rf linux
i=`expr $i + 1`
rm -fr linux.save
_______End of Script______
If you run that script and it generates any output on your computer screen at
all, then you most likely have hardware corruption. I realize this isn't
something one would expect to show up just by upgrading the OS, but keep in mind
that with each version of our product that we release, the kernel typically just
keeps getting faster and faster, and the later kernels can cause problems to
show up on systems that were just barely eeking by before.
I got output from running the script, so it must be hardware.
