This is the debugging output from the spinlock debugging code. I haven't
looked at it closer, but it seems to be fairly obvious..
Thanks to Dave Godfrey for this. The cause _seems_ to be that
sr_ioctl.c: sr_do_ioctl()
does not get the spinlock while it is messing with the requests, in
particular it does a "scsi_sleep()" without holding the spinlock.
The whole function looks fairly suspect: I suspect most of it should be
run with the lock held, but it is nontrivial to completely fix it - we
need to drop the lock for the "down()" call, and I think
"scsi_block_when_processing_errors()" also gets upset if the lock is held
when it is called.
So this should _definitely_ happen on all controllers, you just have to
have the right kind of pattern to the accesses for it to happen (you need
to get a NOT_READY reply to the SCSI ioctl, so this is probably why there
has to be a disk change operation etc).

Hi Linus
I can confirm that the lock-up is repeatable. The sequence is boot-up,
go into X, workman, play a CD, eject from workman, insert a different
CD, lock-up. I was mistaken in the motherboard, it is actually a Tyan
S1662D but all the other details were correct.
I have built a UP kernel with DEBUG_SPINLOCKS (but without the MTRR
feature which would not compile with DEBUG_SPINLOCKS) and this does
not hang. Here is a copy of the message log followed by the message
log for an SMP kernel that hangs.
Hope this is useful.
If there is anything more I can do, don't hesitate. I am afraid my
kernel hacking skills are not up to interpreting the significance of
the messages.
Regards
Dave

[ Linus ] This is where the interesting stuff starts.
[ Linus ] The implication is that something calls "scsi_sleep()" without
[ Linus ] holding the lock, so now when scsi_sleep() unlocks and then
[ Linus ] re-locks the lock, we'll be locked even though the caller
[ Linus ] thought we wouldn't be.
