Hi!
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.
Aye, best wait until we have to start competing with Chromium for memory... The suspicion is that it was the resource allocation failure path.
Yep, my machines are low on memory.
But ... test did not work that well. I have dead X and blinking screen. Machine still works reasonably well over ssh, so I guess that's an improvement.
Well my last remaining 32bit gen3 device is currently pushing up the daises, so could you try removing the attempt to use WC? Something like

on top of the previous patch. Faultinjection didn't turn up anything in eb_relocate_vma, so we need to dig deeper.
With this on top of other patches, it works.
