In this case, it probably means that we sent a transaction to the disk and it didn't return the transaction within 60 seconds. That drive, with the 71xx firmware revisions, is known to be more or less broken for tagged queueing. Since I see the tagged openings message, either one of two things has happened: - You have disabled the quirk entry in cam_xpt.c. - There's something wrong with the quirk entry or quirk entry mechanism, since it is reporting the number of outstanding tags. So, have you changed the quirk entry? There's one other odd, and possibly bad thing there. The above disk is on SCSI ID 7. That's generally the SCSI ID that the SCSI controller is on. What SCSI ID is your controller on? Can you send the full dmesg output from that machine?
