Comment 1 Stephen Tweedie 2002-04-23 11:46:07 UTC

This is the same system that showed an intrusion attempt and and null pointer
dereference in

   https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=63471

Both of the error reports are signs of what looks like random memory corruption.
 We really need to eliminate that possibility before we can look into it as a
kernel fault: 99% of reports like this turn out to be either due to a hardware
fault or a faulty third-party driver (and the suspicion in this case has to be a
rootkit exploit module.)

I'd recommend an overnight run of memtest86 as the first action, and I'd also
try "chkrootkit" (http://www.chkrootkit.org/) to see if there are any obvious
signs of a rootkit module having been installed.

What does the full "dmesg" show for this system?
