Hi
Recently I've upgraded 7-STABLE: Mar 11 -> Apr 24
Everything was fine until I've tried to configure wireless (ath driver,
WPA)
It crashes every time after interface becomes UP,
(I've seen associated in ifconfig output before crash), but before dhcp
finished to get IP.

Any ideas what to do ? Or probably some hints.
Build a kernel with debug symbols and then reproduce the crash.
