Timeouts were lengthened, not shortened recently. This looks like it timed out on the test read in samount...... that's a four (4) minute timeout. The tape driver is very broken in a lot of ways. Use the scsi_sa.c that's on my web page on freebsd.org (http://people.freebsd.org/~mjacob/scsi_sa.c) with a CAMDEBUG kernel that has camcontrol -Ic N:0:0 (you'll have to supply the N for the ordinal bus number the tape is on) and ship me the output. -matt On Mon, 16 Jul 2001, Justin T.
