Hello, Noticed and bisected a rawhide (with the new 6.11-rc0 snapshots) regression to this commit: 0ddd2ae586d2 drm/ttm: increase ttm pre-fault value to PMD size The regression manifests in choppy youtube video playback in google-chrome-stable. https://www.youtube.com/watch?v=uOpl2XNOgMA google-chrome-stable-126.0.6478.182-1.x86_64 VP9 video, Chrome -> Override software rendering list -> on Chrome -> Hardware-accelerated video decode - default enabled No other visible graphics issues. Its a desktop system with Ryzen 7 5700GRyzen 7 5700G IGP [AMD/ATI] Cezanne [Radeon Vega Series / Radeon Vega Mobile Series] [1002:1638] Tested with linus tip and just reverting the commit fixes the issue. Sorry for the brevity, not sure what other details might be relevant. - Yanko
