I finally got an opportunity to reboot and thus take the new kernel
into action -- my system panicked yesterday. :-/

So yes, the problem with the pt(4) driver going mad on a power-on UA
is gone, except that it still prints out a message even in the
!bootverbose case:

(pt0:sym1:0:5:0): SEND(06). CDB: a 0 0 0 2 0 
(pt0:sym1:0:5:0): CAM Status: SCSI Status Error
(pt0:sym1:0:5:0): SCSI Status: Check Condition
(pt0:sym1:0:5:0): UNIT ATTENTION
(pt0:sym1:0:5:0): Retrying Command

For me it's minor, and i can ignore it, but based on experience with
our user base, i know this kind of message makes some people
nervous... (in particular in countries like here, where the people's
knowledge of English is not always that ideal).

Never trust an operating system you don't have sources for. ;-)
