More arla panic and oops info on linux 2.2.1

[Neulinger, Nathan R.]

Today I got three instances of:

XFS Panic: xfs_message_installdata didn't find node!

Shortly thereafter, the machine became non-responsive interactively, but it
was still pingable. Obviously got stuck in a kernel loop, where kernel space
tasks would still work but user space tasks never got control again.

I have also gotten kernel oopses when running various user space
applications, here is the relevant backtrace info from the oops:

Netscape:

TCSH: (ICK, this one looks like it might be my fault
(old_setgroups_syscall), wonder what I screwed up?) Oh, wait, never mind,
that is just an offset. old_setgroups_syscall is a variable in
xfs_syscalls.c. Why it chose that as a base is beyond me.  After the machine
got in this state, I got this each time I tried a command in tcsh. Had to
reboot to clear the problem.
