Hi Alex, I've made a backport of that patch to linux 4.20, but didn't notice any improvements. It looks like, from the logs with drm debug messages, that the issue is happening after the ring tests, while entering X session. Thanks for your suggestion, anyway. I'll try that again once linux-4.21-rc1 comes out.
