Hi Ville,
ef79d62b5ce5 ("drm/i915: Encapsulate dbuf state handling harder")
With that commit the display is not detected anymore, one commit before that it still works. So this one seems to be broken.
Ville, Stanislav, any idea how to fix this?

drm/i915: Encapsulate dbuf state handling harderThat has nothing to do with display detection, so very mysterious.
Please file a bug at https://gitlab.freedesktop.org/drm/intel/issues/new boot with drm.debug=0xe with both good and bad kernels and attach the dmesg from both to the bug.
Everything (hopefully) provided here: https://gitlab.freedesktop.org/drm/intel/-/issues/4013
Please let me know if you need more, or if I can help otherwise to resolve this.
Did you have any time to look into this already?
How do we proceed with this? Saying that this is either "very mysterious" or "very strange" won't fix the regression. :)
Thanks, Heiko
