Hi !

Here is a 2.0.18 Oops. Looks like it happend while loading a
module, probably the floppy module.

I found this while checking the logs becauce I had problems accessing
the floppy drive. lsmod listed the floppy module as "uninitialized".

The floppy module gets loaded by kerneld.

Tried to reproduce it: boot, startx, started xterm -e tail -f logfile,
started dosemu and tried to access the (empty) floppy drive. Result:
total crash, nothing worked any more (no mouse, no keyboard, no
network). Reset, looked into the logs: nothing.
