Yes, you are correct. I used spin_unlock in order to release the local
driver lock
during the scsi_register call, but I forgot that I had the irq 
disabled as
well.
SO the correct fix is to use spin_unlock_irq/spin_lock_irq around the
scsi_register call. Same fix applies to the u14-34f driver.

scsi_register may want to sleep, so that is not a fix at all...

Ooops, I missed the order.  You (and Manfred) are right, 
unlock-register-lock is desired.

ENOCAFFEINE, I plead...
