Hmm, that's not good. 

Can you do the following:

camcontrol stop da1
camcontrol tur da1 -v
[ then you can start it back up with camcontrol start ]

What I want to see here is the sense information coming back from the drive
when it is spun down.

The new error recovery code should be doing the same thing as the old error
recovery code -- sending a start unit.  For some reason it isn't doing the
right thing, though.
