Re: GPU crash when playing video on firefox
1. try to disable c-states in the UEFI
2. test a completely different software stack (eg. *slightly* older ubuntu live system) and see whether you get the GPU to reset there. The other thread is pretty similar, so this might actually be a software problem (likely kernel or mesa)

I am not sure if I have C-State in my BIOS. These are the pages with power related settings, is any of this what you mean?
These are two images of the BIOS settings:

is popOS! 22.04 good? or shall I take ubuntu 22.04? or more recent?

It really doesn't matter, just make sure that HW acceleration is actually invoked.
Nothing there looks like c-states, ppc-adjustment might be interesting…

I ran popOS! 22.04 LTS, and I got interesting results.
- if I ran a youtube video on firefox, it works without a problem. (with hardware acceleration enabled)
- when I ran a video using mpv --hwdec=auto, it crashes.

Re: GPU crash when playing video on firefox
Means FF on popOS! was likely simply not accelerated?
It also means there is *very* much likely a problem with the hardware. I suspect the moment the APU draws some power and starves the CPU.
Can you cause likewise freezes w/o the video HWA, eg. by running some more demanding GL/vulkan demo? (or game)?
Have you looked into the PPC adjustment setting?

I ran https://benchmark.unigine.com/superposition and https://aur.archlinux.org/packages/gputest, they both ran fine without any crashes.
I look into the PPC adjustment settings and see if I see any differences.

Re: GPU crash when playing video on firefox
There's https://bbs.archlinux.org/viewtopic.php?id=306510 - I don't quite yet know how to make sense out of it, but apparently the crash only happens when an external output is in use.
Can you confirm that?

I have tried the different P_States but that didn't change anything.
I have a minipc and only an integrated gpu, so there is only 1 way to connect it to a monitor.

Re: GPU crash when playing video on firefox
Please check whether the monitor is 10bpc (edid-decode, xrandr --props will list that, too) - do you have another monitor?

Re: GPU crash when playing video on firefox
Supports 10-bits/component Deep Color 4:2:0 Pixel EncodingNo, the idea was whether you've another monitor - instead of a fancy 4k wide-gamut display, maybe some sad 1280x1042 office panel from 2008 or so… the other thread links this very much to that specific monitor and yours is 10bpc capable as well …
