Hi Joel, That seems like a genuine bug. Could you file it at the i915 bug tracker with all the requested information to make sure we can take a look at it: https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs Are you able to try different kernel versions to bisect which kernel version/commit introduced the WARN?
