    It's probably still the same problem. The problem is related to a lock
    contention on block devices. For SCSI drivers anyway, whether the scsi
    driver interrupt routine calls the scsi_done() function with interrupts
    enabled or disabled and whether the driver uses a global cli(); for locking
    in the queue routine will determine if the machine is dead, or just the disk
    subsystem is dead.
