Subject[OOPS] vmscan.c:358

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
