Sorry if you don't want emails like this. I added info. to
but people on Gentoo forums said email would be better.
Git bisect lead me to you:

Symptoms are when resuming after pm-suspend, the screen is blank or corrupt,
the keyboard dead, and syslog shows
kernel: [ 81.096666] [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout,
signaled seq=51, emitted seq=52
kernel: [ 81.096671] [drm] IP block:gfx_v8_0 is hung!
kernel: [ 81.096734] [drm] GPU recovery disabled.
or similar. The problem occurs with all kernels since 5.0 up to and including
5.3-rc2. My laptop is:
cpu:AMD A9-9420 RADEON R5, 5 COMPUTE CORES 2C+3G
with integrated graphics:
Stoney [Radeon R2/R3/R4/R5 Graphics] [1002:98E4]
There are several similar reports on the web, most or all for Stoney hardware,
but that might be a coincidence as laptop users are more concerned about
suspend, and there are a lot of laptops with similar integrated graphics
I'm running Gentoo with a custom kernel, the most relevant bits of the config
# CONFIG_DRM_AMDGPU_SI is not set
# CONFIG_DRM_AMDGPU_CIK is not set
# CONFIG_DRM_AMDGPU_USERPTR is not set
If you tell me how, I'm willing to try to collect traces etc.
