Subject: [Bug 218305] Ryzen 7 7840HS gets stuck at 544MHz frequency after resuming after unplugging the power cord during sleep

--- Comment #43 from Peter Ries (ries.infotec+kernel@gmail.com) ---
I have
$ zcat /proc/config.gz | grep CONFIG_AMD_PMF
CONFIG_AMD_PMF=m
# CONFIG_AMD_PMF_DEBUG is not set
Unfortunately I could not reproduce the effect during the test I did right now.
Subjective impression is that the bug occurs less often since 6.8.x kernel.
Testing procedure was:
Plugged - suspend - unplug - resume - OK
Unplugged - suspend - plug back in - resume - OK
Starting plugged - suspend - resume - repeated 6 times while plugged - OK
Resume was done via "systemctl suspend" command on my hotkey "Strg-Super-End"
Then I tried it 3 times by using the lid - same here - it works for the moment.
So it seems to be more random that for Artem. I'll check if un-/plug procedure
helps as a quick fix to not have to reboot when CPU gets stucked again.
I somehow need to find a reliable procedure to run into this bug before it
makes sense to test the patch.
