And then after approximately 1.5 hours on 2.4.19-xfs (XFS CVS snapshot
20020930 patched only with Randy Dunlap's sys-magic 20020314, built
using gcc 2.95.4 running Debian GNU/Linux).

Now in the process running syslogd. Attached kernel-panic-3.out is the
oops.

I did this, as well, and hit a kernel BUG at sched.c:566. My sched.c is
now exactly the same as the one in the XFS tree (which I think is the
same as the one in vanilla 2.4.19). Oops is attached as
kernel-bug-2.out.

System has been up for two hours so far and is thankfully alive. I hope
someone can point me to what the probably cause of this problem is. I
did an xfs_check -- which is from the latest 2.3.1 package -- and all my
XFS partitions are okay. I will be looking for a memory scanning tool
shortly to make sure I don't suddenly have bad RAM, although the problem
doesn't seem to be that.

Thanks again to everyone for your time.
