SubjectRe: [OOPS] repeatable 2.4.8-ac7, 2.4.7-ac6 [I] just run xdos

Dear Eric;

Ok. I oopsed/locked the machine running 'dos' in a vt,
without X in single user mode. Then I did it again, stracing the
session. Unfortunately, the fs was left in such a state, that
fsck completely chucked the logfile out. Then I booted 2.2.18, and
tried. I could not make it oops.
I need to setup a test machine to persue this farther, as
locking and fscking my main box is no fun:) Ill try to get that
strace...

Here are the oopsen, even though I suspect they dont shed any
light:
