Thanks for the input. I realize the urtw(4) and the pseudo rt2870 drivers
may be missing a MODULE_DEPEND macro but this issue is not as annoying
than the repeated page faults happening when the card is trying
to reassociate itself with a router.
I also noticed the same (random) page faults with the run(4) driver as
well but since I don't use a driver
requiring a external firmware to be loaded, I would prefer fixing the
errors in the generic
wireless code happening unconditionally with run(4), rt2870, and
possibly urtw(4). Plus,
a external firmware seems not necessary for using at least the TEW-644UB
