--- Comment #54 from Daan Vanoverloop (vanoverloopdaan@xxxxxxxxx) ---
I can reproduce the issue on my HP Elitebook 845 G10 with an AMD Ryzen 7 Pro
7840U running Linux 6.8.6 with the following steps:

1. Ensure that the power adapter is not plugged in
2. Suspend the machine
3. Wait for 10 seconds
4. Plug in the power adapter
5. Wait for 10 seconds
6. Wake the machine
7. The CPU frequency is now stuck at 544 MHz

When I unplug the power adapter now, the frequency will immediately start
scaling up again. Replugging the power adapter again while the device is awake
is also okay.

I was unable to reproduce the issue by starting with a power adapter plugged in
and unplugging it before waking up. This did not seem to cause any issues.
