And I just noticed there is another regression report bisected to the same change: https://gitlab.freedesktop.org/drm/nouveau/-/issues/388 Two users there are affected by the change; one of them in the 6.6.y series and a revert there was able to fix this. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page. #regzbot poke
