It could be because it is not unlocking the mailbox because it
doesn't recognise the board revision of the apparently new 1542CP.
(What is a CP anyway?)
The following patch makes the possibly rash assumption that any board rev
greater than 0x42 requires this operation. That seems to be the
pattern with all new Adaptec boards.
NOTE: A fix for this is probably
needed for 2.1 since any new Adaptec 1542C is likely to be common.
Please test this and report back if you can.
