Oops - riel vm

Oops - riel vm

As requested by Rick on IRC, I'm forwarding an oops
I got on a UP box with 2.4-test7-pre3.

Sorry, no System.map, but I'll test this myself tomorrow
and supply proper documentation if I can make it break
as well.

Oops attached.

The box runs stable without the rick-vm patch, and it
does get beaten half-way to death daily, so I have a good
reason to believe that either Rick's patch is the fault, or it
triggers some other bug.

Cheers,

Duh !

I sent the wrong oops just before  :*(

The dates fit very bad with test7-pre3...  This is
the right oops.

It seems strangely related to the other one though,
way before we tried riel-vm...

This mail hopefully clears up any mess I left with
the last post, and now I'll promise to shut up until
tomorrow when I can get some better testing done.

Sorry for the confusion,
