Hi Mark, Unfortunately, your commit 34ae7f35a21694aa5cb8829dc5142c39d73d6ba0 ("[CPUFREQ][2/2] preregister support for powernow-k8") causes a power off/ suspend/ hibernation regression on my test box with the Asus M3A32-MVP mainboard (AMD 790 chipset) and the Phenom 9850 CPU. Apparently, the patch causes a crash in a CPU hotplug notifier to happen, but I'm not really sure of that, since there are a lot of stack traces resulting from it and I'm unable to capture them over a serial console. It is sufficient to revert commit 34ae7f35a21694aa5cb8829dc5142c39d73d6ba0 to make things work again. Please advise.
