Description of problem:
I've been getting kernel oops with the message "Unable to handle kernel paging
request at virtual address <address>". This is associated with crashes in X and
gconfd. I'm attaching output from ksymoops. I have run  all of Dell's hardware
diagnostic tests (including memory tests) and have found no hardware errors.
Nothing appears in the BIOS "event log" (such as overheating). I've run
memtest86 overnight on this machine and it did not find anything.

Version-Release number of selected component (if applicable):

Output of "ksymoops < /var/log/messages" immediately after reboot

Last several oops in output resulted in X crashing, no keyboard input possible

I had an unexplained oops today on a single processor Athlon Thunderbird system
running 2.4.18-27.8.0. I suspect this is related. Before upgrading to
2.4.18-27.8.0 the machine had been running fine for over a month worth of uptime.

More output from ksymoops

This happened more or less simultaneously with my keyboard freezing. Not sure
if they are related.

Definitely happens under load

Dell hardware diagnostic tests aren't very good, try memtest86
http://www.memtest86.com  and cpuburn http://users.ev1.net/~redelm/

Comment 6 Tim Keitt 2003-05-20 14:56:44 UTC
Been there, done that. I've run memtest86 overnight and cpuburn. Neither turned
up any hardware errors. They might be there. I just couldn't find them. I'm
going to do a fresh install of RH 9 and see if the problem persists.
