Adaptec 39320A "Card was not paused"

I am having a problem with an adaptec 39320A SCSI card accessing an 
external raid box, (JetStor III 416S).

Host computer is a Dell PowerEdge2650 with a single processor.

6-CURRENT from Saturday has the following relevant dmesg:

Attempts to newfs a bsdlabeled slice results in the following errors:

**snip (lots of debugging output)**

The same thing occurs in both 5.3 RELEASE and 6-CURRENT.  Newfs will 
actually finish though it takes a while, however, attempts to write to 
the resulting filesystem produce the same debugging output as above.  Is 
this a bug or is there something I need to turn off, etc?  I can provide 
the full output to anybody who is interested.
