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.

kgdb does not shows match (why ?):

% kgdb /boot/kernel.bad/kernel /var/crash/vmcore.43

You should use the kernel image with the debugging symbols here. If you
build and install a kernel, you get two kernel images on 7.x;
1) /boot/kernel/kernel (your regular kernel)
2) /boot/kernel/kernel.symbols (with the debug symbols)
