For the record, I believe I'm seeing the same thing with today's
CURRENT. I can trigger the machine crash by copying data from ad2
to ad0.
For what it worth, back in 7.x, I can reliability trigger machine
hang/crash if I access the 2nd disk extensively. It may or may not
related to this issue though.
