Hi,

looks like someone has done it: https://bbs.archlinux.org/viewtopic.php?pid=2059823#p2059823

and the bisect points to:

|# first bad commit: [fc6aff984b1c63d6b9e54f5eff9cc5ac5840bc8c] drm/i915/bios: Split VBT data into per-panel vs. global parts Best, Jerry |

Hi,

It has been reported by multiple users across a handful of distros that
there seems to be regression on Framework laptop (which presumably is not
that special in terms of mobo and display)

Ref: https://community.frame.work/t/psa-dont-upgrade-to-linux-kernel-5-19-12-arch1-1-on-arch-linux-gen-11-model/23171
Can anyone do a 'git bisect' to find the offending commit?
Also, this works for me on a gen 12 framework laptop:
	$ uname -a
	Linux frame 5.19.12 #68 SMP PREEMPT_DYNAMIC Fri Sep 30 07:02:33 CEST 2022 x86_64 GNU/Linux

so there's something odd with the older hardware?

Could be. Running git bisect for 5.19.11 and 5.19.12 (as suggested by the linked forum thread) returned nothing on gen 11 for me.

This is very odd,
