/dev/lpt1 hangs for some reson or another, and refuses to
ever work again. This is a polled port (no IRQ).
echo "anything" > /dev/lpt1 now hangs and fails to respond to
^C. Any further attempts to output to the port will fail
with "Device busy". The (echo "anything") process will not go
away, and FreeBSD gives a warning when attempting to reboot
that a process could not be killed, and advises to use ps -axl.
ps -axl doesn't seem to show anything interesting. After
rebooting, /dev/lpt1 still fails to work.
Not exactly sure. I can do it here by leaving the device
connected to the port turned off and trying to send to it,
but you don't have this device. Anyway, the port seems
permanently locked up and useless at this time.
What makes FreeBSD think /dev/lpt1 is busy?
