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.
