DF-4432 / run.log
# runtime output — decisive run (kldload of dfrnull.ko)
#
# Command (host): dfbsd-qemu/vm.sh run_root 'kldload /usr/src/sys/modules/dfrnull/dfrnull.ko'
#
# The ssh session never returned: the guest kernel panicked inside the
# kldload syscall (see panic.txt for the serial-console capture), so the
# ssh client hung until the host-side 90s timeout killed it. Raw captured
# stdout/stderr of that command was empty. The decisive runtime output is
# therefore the serial console (boot.log), reproduced in panic.txt:
#
# dfrn0: driver didn't set altq_maxlen
# dfrn0: MAC address: 02:df:44:32:00:01
# DF-4432 replica: if_sln.c:949 -> if_input(ifp, NULL, NULL, -1) on dfrn0 (UP)
# panic: ether_input: invalid mbuf or no mbuf packet header!
# ...
# ether_input() at ether_input+0x197

# Guest state after the run: down (kernel in ddb on serial console).
# Guest was restored with `dfbsd-qemu/vm.sh reset with-src`.
