Hello,
I do have two Problem that have appeared just recently. A kernel
built from sources on 06.01.96 runs fine. The kernel with the
problems is built form sources around 22.02.96. (everything
is freebsd-current of course).
TAPE:
dump crashes SCSI-System, mt offline does not work any more.
At the very end of a filesystem dump (does not matter which one)
the whole SCSI-System gives errors like "unit not ready" and
the System crashes shortly after that due to not beeing able to
page any memory pages in/out.
Additionally (with a freshly booted system!)
a "mt offline" does not work any more... (My Dat-Tape
has lost the eject-button, so this is the only way to get the tape
out of if!)
mt -f /dev/nrst0 offline (does not work)
second "mt -f /dev/nrst0 offline" leads to the following error in syslog:
st0(ncr0:2:0): NOT READY asc:4,0
st0(ncr0:2:0): Logical unit not ready, cause not reportable
