I am just thinking aloud ... Boot log in the bugzilla shows: CPU0: AMD Turion(tm) 64 Mobile ML-34 stepping 02 So it seems that the hardware just dislikes CONFIG_CPU_IDLE. I haven't dealt with that cpuidle stuff in the past. Now I am wondering with which platforms that code was verified. And yes, I know the code was in -mm for a while. But maybe the test coverage on AMD platforms was not that high? What about making CONFIG_CPU_IDLE dependent on EXPERIMENTAL for the time being and remove EXPERIMENTAL when some more testing has been done?
