Something breaks in the event handling and event reference counting. Unfortunately my vacation is pressing on, and I am not sure if I have time to debug the issue further before that. Anyway, I have attached the boot log with the following WARN dumps: ---------------------------------------------------------------- [ 12.203874] WARNING: CPU: 0 PID: 208 at drivers/gpu/drm/drm_atomic_helper.c:2329 drm_atomic_helper_commit_hw_done+0x144/0x168 [drm_kms_helper] [ 12.217682] WARNING: CPU: 0 PID: 208 at drivers/gpu/drm/drm_atomic_helper.c:2329 drm_atomic_helper_commit_hw_done+0x144/0x168 [drm_kms_helper] [ 232.156231] WARNING: CPU: 0 PID: 1315 at drivers/gpu/drm/drm_atomic_helper.c:2329 drm_atomic_helper_commit_hw_done+0x144/0x168 [drm_kms_helper] [ 232.472068] WARNING: CPU: 0 PID: 1315 at lib/refcount.c:28 __drm_atomic_helper_plane_destroy_state+0xd0/0xe0 [drm_kms_helper] [ 240.611129] WARNING: CPU: 0 PID: 1317 at drivers/gpu/drm/drm_atomic_helper.c:2329 drm_atomic_helper_commit_hw_done+0x144/0x168 [drm_kms_helper] ---------------------------------------------------------------- The first two came at boot time when setting up the fbconsole, the ones after that came when I tried to use kmstest[1]. The fbconsole came up, but nothing after that works. I am back from vacation in the beginning of august, so there may be some time before I can debug this further.
