Hi,

This OOPS is one I've seen on a number of different systems. The first one 
is a decoded one fished out of /var/log/messages, the second one I typed 
over from the console and decoded by hand.

In the second case, the system is still alive, but all new processes 
created create the same oops again, with a slightly different stack, and 
the process is the OOPS is the process that was just created.

I've also seen similair OOPS'ses on usenet, with a similair call trace.

Sysinfo for the two OOPS'ses below :

[root@igmar igmar]# uname -a
Linux igmar.base.jdimedia.local 2.4.20 #1 Tue Dec 24 21:42:30 CET 2002 
i586 unknown
[root@igmar igmar]# cat /proc/modules
vfat                    9696   3 (autoclean)
fat                    30496   0 (autoclean) [vfat]

System is a AMD K6-2.


Please contact me directly if more info is needed.



	Regards,


		Igmar
