For the last few months I have been experiencing occasional panics from intel_frontbuffer_put(), while running OBS-studio. An excerpt from the backtrace: intel_frontbuffer_put() intel_user_framebuffer_destroy() _drm atomic_helper_plane_destroy_state() drm_atomic_helper_plane_destroy_state() drm_atomic_state_default_clear() intel_atomic_state_clear() __drm_atomic_state_free() intel_atomic_cleanup_work() linux_work_fn() I found a freedesktop.org bug report for an issue that looked related[1]. Unfortunately the patch attached there does not apply to Linux 5.4 corresponding to what we have in drm-kmod[2]. I've backported the patch and applied it against the 5.4-lts branch in the drm-kmod repo, and the issue has not recurred. My patch is in a pull request at [3], and available as a patch file at [4]. Review and/or testing is very much appreciated.
