This is a nice Adaptec cable *without* a built in terminator, right? > This happens when the drives are 'busy' (but not totally thrashed)... Does it only happen before the tag count is reduced, or does it happen regardless of how man, "tagged openings now X" messages you see for the offending target? It looks like, at least for this particular rev of the firmware on these drives, the drives continue to take in transactions above and beyond their internal tag limit, hang up probably blocking on a resource shortage, then do not properly clean up all pending transactions when we whap them with a Bus Device Reset Message. The Adaptec driver then starts seeing transactions returned by the device that are no longer pending (they should have been killed by the BDR) and complains. You should look to see if there is later firmware available for this drive. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
