Thomas Zimmermann <tzimmermann@xxxxxxx> writes:Invoke drm_plane_helper_funcs.end_fb_access before drm_atomic_helper_commit_hw_done(). The latter function hands over ownership of the plane state to the following commit, which might free it. Releasing resources in end_fb_access then operates on undefined state. This bug has been observed with non-blocking commits when they are being queued up quickly. Here is an example stack trace from the bug report. The plane state has been free'd already, so the pages for drm_gem_fb_vunmap() are gone.

Alas the problem doesn't seem to have been resolved entirely, because I've had the following Oopses:
Thanks for testing. I think I got the test in drm_atomic_helper_cleanup_planes() wrong. I'll seend out an update soon.
