I ran

-drive format=raw,file=ubuntu.raw,if=virtio \
-n
I am by no means a kernel expert, but Tomeu asked whether I could
review this. Generally the patch looks okay, it applied (on top of

Hello,
i think it got it nailed, please try the attached patch (it is against
11-pre4, but it should work against all test11).
Explanation:
with test7-pre6 in the imm-module the new scsi - code was enabled (see
imm.h).
This causes the locking of the io_request_lock in scsi_register_host

A bug i had with kernel version 2.4.0-test9 is still there, but there are

The iomega-drive is usable after the modprobe and despite of
the lockup.

I was told that I should see if the bug is repeatable with a vanilla gcc
(and not pgcc).
/proc/version is now:
