Thanks for the patches. I assume this should fix problem from
"5.9-rc1: graphics regression moved from -next to mainline" thread.

I have applied them over current -next, and my machine seems to be
working so far (but uptime is less than 30 minutes).

If the machine still works tommorow, I'll assume problem is solved.

Best regards,
