Recent 2.1.XXX kernels (probably since 2.1.102) lock up during the bus
scan of the PAS16 SCSI driver. The machine hangs with interrupts
disabled. The following sti() seems to cure the problem, but I'm not
sure if this is a proper solution. Perhaps someone more familiar with
the code can take a look at this?
