Issue #2685 has been updated by xbit.
I have checked this issue again and noticed some strange behaviour. If I change several BIOS (AMI BIOS) settings, the freeze occurs. Below is a list of the settings and how they need to be set. - Advanced Clock Calibration: Disabled - PCIPnp: Active State Power Management: Enabled - Northbridge Internal Graphics: FB Location: Below 4GB - PCI Express: NB-SB VC1 Traffic Support: Enabled Whenever I change one of these options, the systems freezes and restarts when running 'wpa_supplicant -Dbsd -iwlan0 -c/etc/wpa_supplicant.conf'. With the settings above, I can run wpa_supplicant and dhclient and the network seems usables. I just made a quick ping to another machine. The most strange behaviour is when I start wpa_supplicant in the background (with &), the system immediately hangs and resets. I upgraded yesterday to 4.0.5. ---------------------------------------- Bug #2685: configuring ath0 freezes the system http://bugs.dragonflybsd.org/issues/2685#change-12633 * Author: xbit * Status: New * Priority: Normal * Assignee: * Category: Driver * Target version: 4.0.x ---------------------------------------- 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.
