I have two disks on the scsi bus, but it only complains about da0. (I see the _exact_ same error message as above). I applied your patch, but still see the same message. (exactly the same) What I noticed though, because my da0 (100MB) is totaly dedicated to swap, if I boot single-user without executing 'swapon', it would not show the message during reboot. I can read/write _just_ da1, then reboot, and no message. If I do a 'swapon' in single-user mode, I see the error message after 'halt'ing. In other words, if the controller does not access da0, I will not see a message.
