2.6.17.2 kernel bug?

[Greg Scott]

This may be a hardware problem but I thought I should tell somebody.
It's running on a Dell Optiplex GX110, p3 733mhz, 256MB.  Below is an
extract from /var/log/messages.  I noticed these messages while I was in
a telnet session to that system.  Right now Nautilus on the console is
frozen in its screensaver.  This particular system is in a lab so I can
do what I want with it.  

Like I said, this could be a hardware problem, or maybe it's a kernel
bug.  Apologies in advance if the below wraps.  In case the output below
is unintelligible, I will also attach bug.txt to this email.  It
contains the same output I pasted in below.
