Please don't top-post :(
Anyway, should be fixed in the next round of releases in a few days, if
not, please let us know.

Hi Greg,
seems the RCs work out. 4.19.279-rc1 and 5.10.176-rc1 were tested by a
user who had the issue on i915. In 5.15 series the drm patch got
reverted. I only see "drm/i915: Don't use stolen memory for ring buffers
with LLC" there as "drm/i915: Don't use BAR mappings for ring buffers
with LLC" was reverted with 5.15.101.

So is 5.15.y ok or not? Sorry, I could not parse your response here.

Hi Greg,
yes, 5.15.y seems to work. You could even re-add the reverted patch from
5.15.101 as we also have tested with it applied on top of 5.15.104-rc1.
