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:

Yes, the issues do not happen with those patches applied.
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**
Here is that line:
[ 12.085196] [drm] PSR support 1, DC PSR ver 1, sink PSR ver 3 DPCD caps 0x7b su_y_granularity 4 force_psrsu_cap 1
