Description

Loading if_ath works, but when configuring the device the system locks up/freezes.

System has been upgraded from 3.6-RELEASE via buildworld, installworld. Kernel is GENERIC_X64_86 and HEAD is 358af07.

Running "ifconfig ath0 up" works.

Then calling "ifconfig wlan0 create wlandev ath0" freezes the system.

I discovered the follwoing kernel message when trying to configure the device using /etc/rc.d/netif.

ath0: _ath_power_restore_power_state.refcount=0?

I also applied the change from http://lists.dragonflybsd.org/pipermail/commits/2014-June/270210.html via cherry-picking, but no changes.

The 3.6-RELEASE have been used successfully with the same hardware.

Here are the ath related snippets from the dmesg output:
