It's not coincidence. Both of you have polling based SCSI controllers
where the drivers sit in tight loops waiting for things to happen inside
of a spin_lock_irqsave(). There's nothing intelligent that can be done
until the locking in the drivers/mid-level SCSI code is redone except
switching to a SCSI controller/driver combo that doesn't spin wait for
things like individual bytes on the SCSI bus.
