Hi, just found that
echo 0000:06:01.0 > /sys/bus/pci/drivers/analogy_mite/unbind
does not do the same thing as
analogy_config -r analogyN
in fact it leaves the system in a state where using the driver results
in a kernel OOPS.
Will try to look into it further tomorrow...
OK seems like we have some interrupt cleanup problem, the following
command sequence:
modprobe xeno_native
modprobe analogy_ni_pcimio
sleep 1
/usr/local/sbin/analogy_config analogy0 analogy_ni_pcimio 6,1
/usr/local/sbin/analogy_config -r analogy0
rmmod analogy_ni_pcimio
rmmod analogy_ni_mio
rmmod analogy_ni_tio
rmmod analogy_8255
rmmod analogy_ni_mite
rmmod xeno_analogy
sleep 2
modprobe xeno_native
modprobe analogy_ni_pcimio
sleep 1
/usr/local/sbin/analogy_config analogy0 analogy_ni_pcimio 6,1
