Comment 24 for bug 1945221

I would still likes to know what MSR 0x64F says, as per comment #20.

Yes, thermald should have been disabled for all of this stuff, and I thought it was.

Recall one the askubuntu threads, where I suggested writing 0x4005C to MSR 0x1FC. Do so at your own risk.

Your hardware seems to have issues, and assems to be asserting the external PROCHOT bit.

If it were me, I would disable turbo boost in BIOS, and boot into passive mode with the schedutil governor:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=passive cpufreq.default_governor=schedutil"
