I've written 2 patches 2 address this and asked users to test Fedora-kernel
scratch-builds with those patches added.
Thx for working on this, I have a friend that is affected by this.

Given that we are getting more and more bug-reports about this I think
that we should be do something about this downstream. Upstream seams
to be aiming for fixing things, rather then reverting, so going with
i915-fixes.patch will stay the closest to what I expect to land in
5.10.y and 5.11.y at some point.
Out of curiosity: Upstream means "the drm/i915 folks here"? What about
GregKH? Is he aware of this? He's not Linus, but he hates regressions
nearly as much afaics, so why not maybe he is willing to revert those
patches quickly and thus maybe force the drm/i915 folks into action?
Ciao, Thorsten
