Some notes:
I'm not a kernel hacker.
Kernel 2.0.x works well.
I have only tried kernel 2.2.0-pre1,2.
After the oops occures, it was not possible to reboot the computer
by CTRL-ALT-DEL. (kernel 2.2.0-pre1)
Booting kernel 2.2.0-pre2 crashes also (the output above show it),
but CTRL-ALT-DEL works.
I'm not sure, but i think the problem is in
file linux/drivers/scsi/gdth.c , function <gdth_sync_event>.
Further more, i hope this bug-report is quite completely and not
too much off-topic, even if the oops occures only at my system.
