Look at the first reply for answer.
Which Linux distro are you using?
Archlinux 6.15.5-arch1
Bios 3.9
So I was compiling the linux kernel and I noticed a sudden slow down of the time it took to compile each module. I fired up s-tui and I saw that the thermals were ok (below 70 celsius) but the packge power draw was 15W.
At first I assume that this was some kind of throttle but after a while and with the laptop completely cold I firre up the s-tui stress mode, and package power consumption was still 15W. A reboot was needed to fix the situation.
After a while and while already stuck at 15W power draw I could see “Sensor2,0” which I believe corresponds to the nvme pcie
nvme-pci-0200
Adapter: PCI adapter
Composite:
temp1_input: 57.850

Sensor 1:
temp2_input: 57.850

Sensor 2:
temp3_input: 85.850
temp3_max: 65261.850
temp3_min: -273.150
Some info I gathered while compiling the linux kernel:
ryzenadj -i
