Subject: PROBLEM: Oops: 0002 [1] SMP
[1] Summary:
Kernel Reports Oops: 0002 [1] SMP and the system becomes unstable
[2] Full Description:
Sometimes, randomly i get this Oops message and the system becomes
unstable. By unstable i mean all applications segmentation faults when i
execute (after the Oops). Sometimes X crashes, sometimes the machine
just reboots (the reboot might be other problem tho).
This happens with kernel 2.6.20 and with 2.6.21-rc7. Was happening with
2.6.20 so i tried 2.6.21-rc7 and this also happens.

In this case it appears to happen when using evolution but it happens
with other apps too.
