Following up to myself with a bit more info, I played around a little bit more, and discovered that yes, we do have some atio's waiting, and if we get a bus reset one of these gets sent back. I also discovered that ahc_intr() never gets called during the rescan of the bus whilst in target mode. To me at least this would suggest that the controller is never being selected, or failing that the controller is never telling the device driver that it has been selected. Unfortunately we do not have any hardware here for examining SCSI busses, otherwise I could find out whether the controller was responding to the select with BSY (well, we have the logic analyser, but nothing to plug it in with). The other thing is that I only get bus reset intermittantly, which worries me. By this I mean that I can do a camcontrol reset <bus> on one machine, and the other machine doesn't always pick it up (I don't get the "Somebody reset bus %d" message). I doubt this helps particularly much though. -- Iain To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
