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.

Thanks,
Rafael
