crash dump log
When powerd is running it always reboots (or hangs) my system after a while. I
start powerd with "-a adaptive" or "-a hiadaptive" flags and it starts to scale
cpu clock speed. After a while i walk away from my pc to watch some tv, eat
dinner, etc., but when i return to my pc it always has rebooted.
This has been an issue starting from 10.0-RELEASE (i'm no on 10.1-STABLE
r276610 now).
CPU: AMD A8-5600K APU with Radeon(tm) HD Graphics (3593.35-MHz K8-class CPU)
I have added crash dump (core.txt.2) and powerd output from when the utility
was started till the point it freezes (powerd.log).
How to reproduce: start powerd utility on AMD system and then let powerd to
scale down cpu to minimum and then the pc reboots or hangs.
