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. -- You are receiving this mail because: You are the assignee for the bug.
