See the comment at ~ line 1613 of sys/dev/buslogic/bt.c or just search for "QUEUE_FULL" until you find the comment. If you could stick a printf in there to verify this, that would be great. In the mean time, I'm going to try to get some information out of Mylex on this issue. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
