I have same hardware with latest BIOS. Running Arch based Endeavour OS. Kernel
6.16.3-arch1-1 ATM.

I still have this annoying bug. Thought it was gone, but obviously I didn't
unplug while in suspend that often. But the last days I worked more away from
desk and needed to unplug when suspended and irregularily (every 5th time may
be) the CPU is stuck in low states 544MHz.
