iwn0 hangs randomly when starting the machine

[Erich Dollansky]

Hi,

since I upgraded to r263767, I have the following problem:

Wireless does not start all the while. When it does not start, it hangs
then forever. wpa_supplicant's state in top is then '-'. If I start
wpa_supplicant by hand, it will hang and it cannot be stopped by
control C. The light indicating that wireless is up is never on in this
case. Rebooting the machine solves the problem. I did not find any
other way to solve as the wireless related commands will hang.

When the wireless network comes up, I can work just normal.

Erich
