I dumped one of my filesystems to the tape and everything was going fine till it got all done and rewound the tape. At that point I go the following sequence of messages on the console, followed by a system hang (no panic, just hang): ahc0: Target Busy ahc0: Target 6, lun0 (st2) timed out ahc0: Target 6, lun0 (st2) timed out ahc0: Target 6, lun0 (st2) timed out ahc0: Target 6, lun0 (st2) timed out Thought you'd like to know. Let me know if there is anything I can do to help track it down. Note the tape did in fact successfully rewind and the drive allowed me to remove it (whilst the system was hung). -- Bob Willcox bob@obiwan.pmr.com (or obiwan%bob@uunet.uu.net) Austin, TX
