I have noticed some instances where a new kernel will come up with rfkill hard
blocked even when the switch is in the on position, and in one case where the
box does not even have a switch. These have been with b43, thus no hang.
Unloading/reloading the driver fixes the issue, which I think is caused by an
uninitialized variable in rfkill. Thus far, I have not found a cause, and have
not previously reported it.

In any case, booting the computer with the rf switch off should not cause an
infinite loop.
