Please also find below a stack trace produced with option KDB_UNATTENDED for the rt28700 driver (if_rt28700). On another side note, I have not being able to load the runfw firmware module anymore after having updated the src tree for 8.2-STABLE ? $ sudo kldload /boot/kernel/runfw.ko kldload: can't load

would be acceptable solution however as the rt28700 driver doesn't depends on a firmware module, I have no choice currently to stick with the former rt28700 driver. I notice however that there's still some random page faults occuring with the run(4) module, but are non-fatal with option KDB_UNATTENDED... :) Cheers!
