I've seen this with the ida(4) driver as well, though only on re-insertion
of a hotswap disk.  Failure was the same.  With the system cracked open
and the status LEDs on the controller available for viewing you could see
when the controller locked up.

After going over the driver and instrumenting the interrupt handler and
installing a watchdog timeout routine I see no way that this condition
could be caused by the driver, unless we're supposed to be doing something
that we don't know about.

What model CISS card do you have?
