Subject: amdgpu, 5.11.0, suicide when input of monitor is switched

Hi all

After switching inputs of the display I use (two computers are
connected, one via DP and the current one via HDMI), the AMD GPU I use
stopped sending signals to the display.

The kernel log showed the following:

[  262.300879] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:77:crtc-0] flip_done timed out

I was running a KDE/Plasma session (5.21) on top of Debian/unstable.
The xsession-error log only shows
   kscreen.kded: Config does not have at least one screen enabled, WILL NOT save this config, this is not what user wants.
and XOrg log didn't say anything.

I tried switching to the console and back, but the screen didn't come
back.

Thanks for any suggestion

Norbert
