           Summary: amd_pstate=active reset computer

Hello!

I have a ASUS TUF A17 FA706QR laptop. Ryzen 5800H, nvidia dgpu.

I have installed Ubuntu Desktop 24.04 LTS with kernel 6.8 and the laptop
started to reset shortly after booting: from a few minutes to 30 minutes,
nothing in the logs.
Before I had Ubuntu 20.04 with 5.15 kernel, no problems, but amd_pstate was not
active.
Reset occurs by leaving the laptop at idle or doing something like playing an
youtube video.
I also tried kdump without getting any dump files.

I noticed that the processor runs at lower frequencies than 20.04, so do the
fans, most of the time at 0 rpm. Temps 50-70 degrees.

I ran stress on one core, youtube play in the same time, cpu temp ~90 degrees,
no reset!

I switched the power profile to Performance and it didn't reset.
It only happens on Balanced or Power Saver profiles.

Next step was amd_pstate=passive, reset only on Power Saver.

The fix was amd_pstate=disable. No reset at all

Not happening on other Asus laptops with Ryzen 6800H, Lenovo (no Nvidia) 5800H,
6800H, 7840HS with amd_pstate=active, Ubuntu 22/24, 6.5 and 6.8 kernels.


Thanks!
