--- Comment #1 from Greg V <greg at unrelenting.technology> ---
Just encountered this problem. (Also seems related: bug 221621)

Looks like Linux is writing the MSR in the loop
https://github.com/torvalds/linux/blob/35dbba31be52c59a89bd96d49f170999d57c9234/drivers/cpufreq/powernow-k8.c#L169-L175
but we write it once and then only check in the loop.

This shouldn't fix anything but I'll try…
