I recognize that, however, what I should have mentioned in my last
mail message is that the disk was returning SCSI command completions while
still holding on the SCSI command and considering it to occupy a queued
command slot. As a result, the number of tagged commands the SCSI driver
thought it had outstanding did not agree with what the device had. I
certainly had not expected this behaviour.
