Issue #2685 has been updated by swildner.
Can you give us a dump in the failing state? Backup the working kernel by copying the /boot/kernel directory to /boot/kernel.bak. Then, revert the patch, recompile/install the kernel and bring it to the point where it hangs. Then, hit CTL-ALT-ESC to break into ddb. At the "db>" prompt, do "call dumpsys" (it should dump to disk then and countdown numbers on the console). When it is finished do "reset" to reboot. At the loader menu, it will then give you an option (I think it's "b") to boot the previously backed up working kernel.bak. Upon coming up, it will save the dump to /var/crash. Then, tar/xz the kern.XX and vmcore.XX with the highest number from /var/crash and put it up somewhere from where it can be downloaded. ---------------------------------------- Bug #2685: configuring ath0 freezes the system http://bugs.dragonflybsd.org/issues/2685#change-12091 * Author: xbit * Status: New * Priority: Normal * Assignee: * Category: Driver * Target version: 3.8.0 ---------------------------------------- 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.
