The last time I heard of this problem, the guess was that the BusLogic firmware doesn't deal with 'Queue FULL' very well, so you have to limit the number of transactions sent to the drive to something smaller than CAM's default. Add a quirk entry in sys/cam/cam_xpt.c that reduces the tag count to ~32 (depending on the drive) and your problem will likely go away. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
