CPU frequency stuck with 6.x kernel

Thinkpad T495s with Ryzen 3700U here. With the update I changed from kernel 5.19 to 6.0. Since then under load but way before reaching any kind of temperature or power limit, the CPU is stuck to 399 MHz, irrespective of any frequency, governor settings etc. Booting back into 5.19 everything behaves normally again.

can you try
with 5.19

inxi -Fza
sudo cpupower frequency-info
sudo turbostat ( first lines Q or Crtrl+C to exit )

with 6.0.x

uname -a
sudo cpupower frequency-info
sudo turbostat ( first lines Q or Crtrl+C to exit )

Happened all throughout last week, but now that I’ve reported it, 6.0x behaves normally again…:confused: Will investigate some more and report back with the info you asked for if I can reliably reproduce after all
