--- Comment #14 from Mario Limonciello (AMD) (mario.limonciello@amd.com) ---
I read through this thread and I currently think that Artem and Dan have
encountered two separate bugs.
@Artem:
Under the presumption that ryzenadj is actually retrieving the correct values
for STAPM, PPT FAST, and PPT SLOW I want to ask if this is tied to a specific
power adapter, or sequence of events. Like suspend on power, resume on battery
or suspend on battery resume on power.
If there is a linkage between any of those, then I think this is "most likely"
an HP EC bug.
@Dan,
Can you reproduce this if you manually always set the scaling governor on all
CPUs to "performance" before you reboot?
