Kernel 2.6.32 Panic: unable to handle kernel paging request at (...)

[Pedro Francisco]

Hi!
I'm having a Kernel panic on 2.6.32 which I can't steadily reproduce.

Last time I was able to change to a TTY and saw:

BUG: unable to handle Kernel paging request at (...)

Upon reboot my /var/log/messages had many messages like this (more text below 
it):

So, what shall I do?

The new hardware I'm currently using is somewhat unrelated, an Ubiquiti SRX 
wireless card (ath5k) and a GPS through a Bluetooth connection.
Any ideas on how to trigger the event?

Anything at all?
(I'm memtesting the memory tonight).
