Still no joy. I still think drm-current-kmod is involved because these are produced just prior to the panic whereas the dmesg buffer is clean of them without r353149. Unread portion of the kernel message buffer: WARNING !drm_modeset_is_locked(&crtc->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 577 WARNING !drm_modeset_is_locked(&crtc->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 577 WARNING !drm_modeset_is_locked(&dev->mode_config.connection_mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper .c:622 WARNING !drm_modeset_is_locked(&dev->mode_config.connection_mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper .c:622 WARNING !drm_modeset_is_locked(&plane->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 821 WARNING !drm_modeset_is_locked(&plane->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 821 WARNING !drm_modeset_is_locked(&plane->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 821 WARNING !drm_modeset_is_locked(&plane->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 821 WARNING !drm_modeset_is_locked(&plane->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 821 WARNING !drm_modeset_is_locked(&plane->mutex) failed at /usr/local/sys/modules/drm-current-kmod/drivers/gpu/drm/drm_atomic_helper.c: 821 <4>WARN_ON(!mutex_is_locked(&dev->struct_mutex))WARN_ON(!mutex_is_locked(&de v->struct_mutex)) <4>WARN_ON(!mutex_is_locked(&fbc->lock))WARN_ON(!mutex_is_locked(&fbc-> lock)) My servers (no X11) work well with this. It's only drm-current-kmod that has gas with this rev. I've cc'd the maintainer of drm-current-kmod (x11@). -- Cheers, Cy Schubert <[email protected]> FreeBSD UNIX: <[email protected]> Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few.
