X-Mailer: ELM [version 2.4 PL23] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Length: 1559 Sender: owner-current@freebsd.org Precedence: bulk I am trying to put a very small text file onto a SCSI DAT tape using "dd". When I do a "dd if=FILENAME of=/dev/rst0" the light on the DAT drive goes on and the machine hangs. If I am in text mode (as opposed to X) using syscons I can switch between consoles but there are no cusors in any of them. Also (not suprisingly) CNTL-ALT-DEL doesnt do anthing. (i.e. the machine seem pretty well hosed). Normall dump/tar seem to work without problems. Any ideas what might be up? Here is (most of) my dmesg output: (aic0 is a 1522 is this case.)
