Subject[2.6.27.5] kernel panic (unable to handle paging request)
When running 2.6.27.5 I'm experiencing kernel panics after some random
amount of time. I'm not quite sure what triggers them, the first time it
happened after 5 days uptime, the second time after 1 day, always doing
the same random stuff. I've copied the Oops message from screen by hand
(at least the readable part of it):

Fixing recursive fault but reboot is needed!

Kernel panic - not syncing: Fatal exception in interrupt.


It looks like many things are going wrong at once.
I'm now back running 2.6.27.4 which is and has been runing fine.
The machine itself is an AMD Athlon XP 2000+ with an ASUS A7N8X (having
an nfroce2 chipset) with 512 MB RAM and some Geforce TI 4800 iirc.
Any help with this issue is really appreciated.

greetings
