Subject: Kernel Oops problem

Dear all,

A server of mine has recently been suffering a Kernel Oops.  The following
link
http://users.sosdg.org/~qiyong/lxr/source/Documentation/oops-tracing.txt?v=2
.6.16 contains information on how to trace and log a Kernel Oops problem. 
The link offers your email address if, to quote If you are totally stumped
as to whom to send the report.  Please accept my apologies if I have the
wrong information for reporting a Kernel Oops problem.  I believe the
ksysmoops utility in my case is useless, again to quote the above link
NOTE: ksymoops is useless on 2.6.; hence, I am stumped.

The server in question is running the following:

	home# uname -a
	Linux <xyz> 2.6.9-55.0.9.ELsmp #1 SMP Thu Sep 27 18:27:41 EDT 2007
i686 i686 i386 GNU/Linux

	home# cat /etc/redhat-release
	CentOS release 4.6 (Final)

The Oops seems to occur at a random interval, but, has constant detail in
the report:

	home# tail -n80000 /var/log/messages  | grep  "Oops"
	Mar 10 19:15:58 home kernel: Oops: 0000 [#1]
	Mar 11 01:50:33 home kernel: Oops: 0000 [#1]
	Mar 12 10:44:38 home kernel: Oops: 0000 [#1]
	Mar 15 00:58:24 home kernel: Oops: 0000 [#1]

The detail obtained so far is:

Any advice either on the correct way to report this or extra commands to run
