Is it possible for you to test with another mac80211-based wireless
device? I cannot think of any possibility for the system to lock up when
b43 is using PIO.

When the freeze occurs, how long do you leave it? There are some CPU
lockups that take as many as 2 minutes to be recognized by the kernel.

In Archlinux, how difficult is it to incorporate source from an external
tree and build the kernel?
