Created attachment 290583 [details] 0001-drm-amd-display-Force-add-all-CRTCs-to-state-when-us.patch
Just booted to 5.8-rc7 with this patched in locally (and the g320+ reverts /not/ patched in). So testing, but noting again that the bug can take a couple days to trigger on my hardware
This doesn't seem to trigger the bug at all for me, tho there's the expected slowdown/judder from force-syncing all CRTCs as detailed in my last couple comments. But with the more serious side effects mnrzk is seeing with it, it's clearly not useful as an even temporary mainline candidate.
I'll be testing mnrzk's patch now. Hopefully it'll be good enough for the quickly approaching 5.8, tho dev consensus seems to be that a deeper rework is needed longer-term.
