Hi August,
I've sent a fix here: https://patchwork.freedesktop.org/patch/504993/
It's not the most ideal fix, but it should address the regression. Let
me know it works for you.
Thanks!
Leo

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
