When I woke today I found I'd gotten the following oops,

Feb 25 06:27:37 burocracia kernel: Unable to handle kernel paging request at virtual address 00020008

which decodes into

and a series (2 or 3, not sure) of "kernel BUG"s, finishing with
"deactivating console" or words to that effect. On reboot I'm
afraid the only bit that survived after the oops was

Feb 25 06:27:39 burocracia kernel: kernel BUG at exit.c:458!

the box is debian unstable, w/reiserprogs from the reiser site.

Let me know if any other info'll be useful.
