hwpstate_intel hangs kernel

I updated my sources from 20200113 to 20200124 and after that my laptop
hangs during boot.

The machine is a Lenovo Thinkpad X1 yoga with a core i7-6500U cpu and 8Gb

It hangs during kernel boot and the last message printed on console is:
hwpstate_intel0: <Intel Speed Shift> on cpu0

I reverted commits
and recompiled the kernel, which then boots just fine.

Interestingly, the hwpstate_intel code worked fine on my workstation, with
a Intel i7-7700 cpu.

I set debug.hwpstate_verbose=1 in loader.conf in hopes of getting more
info, but I could not see any additional information.

Best regards
