This run on my HP 15-bw0xx
cpu:AMD A9-9420 RADEON R5, 5 COMPUTE CORES 2C+3G
with integrated graphics:
Stoney [Radeon R2/R3/R4/R5 Graphics] [1002:98E4]
I get the same symptoms as above;
a more involved scenario that may shed light is to switch to a tty and stop=
xdm
(and hence sddm) so I have no graphics sessions running.
pm-suspend followed by resume works and brings me back to the tty, but when=
I
then start xdm, I get a broken screen, usually garbage or grey, and syslog
shows something like the following:

If I enable amdgpu.gpu_recovery=3D1

I can probably run diagnostics or collect a trace if someone tells me what =
and
how.
The problem persists - I still get it running kernel 5.2.1
