It seems that after a certain number of repetitions of a failing command, the entire card locks up and the sequencer always returns SAM_STAT_BUSY to any new commands. This is a bit of a problem for the scsi mid-layer because it blindly always retries SAM_STAT_BUSY and SAM_STAT_QUEUE_FULL. The only way to recover from this is to issue a bus reset. This condition, I think, is what causes some of the hang reports about this driver. However, I think I see the code in the sequencer which is causing it (target_cmdphase) but I don't have enough information about the sequencer to fix this.
