With this change situation extremely improved. I am even could reboot computer after it without pushing power button for 5 seconds.
But:
1) I am still couldn't return to desktop GNOME shell (Not Alt -Tab nor "Win" button does not help) (maybe it was not supposed?)Anyway currently after GPU resset possible work only in terminal.On photo how looks monitor after GPU reset.
2) I got a lot of messages "[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser -125!" I suppose not everything went according to plan.
This is expected. After a GPU reset all applications using the GPU need to be restarted unless they are coded to properly get GPU resets and can properly reset their contexts. At the moment no very few apps use GL robustness extensions so you'll need to restart X, apps, etc. after a GPU reset because all of the applications' GPU data is lost during a reset.
