Hi August, thanks for the log.
It seems the eDP panel does not fully satisfy the amdgpu requirements for enabling PSR SU, but we're enabling it anyways.
I suspect it may be due to the "DP_FORCE_PSRSU_CAPABILITY" bit being set in it's DPCD registers, I'm checking with some devs to see if that is expected.
In the meantime, can you give these two hacks a spin? Let me know if this helps with the glitches and system hangs: https://gitlab.freedesktop.org/-/snippets/7076
Also the dmesg, in particular this line: > [drm] PSR support 1, DC PSR ver 1, sink PSR ver 3 DPCD caps 0x70su_y_granularity 4 force_psrsu_cap **X**
Thanks, Leo
