Seems like disable can race with complete_flip() in process of disabling a crtc, leading to: [ 49.065364] Call trace: [ 49.071441] [<ffffffc00041d5a0>] mdp5_ctl_blend+0x20/0x1c0 [ 49.073788] [<ffffffc00041ebcc>] mdp5_crtc_disable+0x3c/0xa8 [ 49.079348] [<ffffffc0003e7854>] disable_outputs.isra.4+0x11c/0x220 [ 49.085164] [<ffffffc0003e7afc>] drm_atomic_helper_commit_modeset_disables+0x14/0x38 [ 49.091155] [<ffffffc000425c80>] complete_commit+0x40/0xb8 [ 49.099136] [<ffffffc0004260ac>] msm_atomic_commit+0x364/0x398 [ 49.104430] [<ffffffc00040a614>] drm_atomic_commit+0x3c/0x70 [ 49.110249] [<ffffffc0003e67b8>] drm_atomic_helper_set_config+0x1b0/0x3e0 [ 49.116065] [<ffffffc0003f99bc>] drm_mode_set_config_internal+0x64/0xf8 [ 49.122746] [<ffffffc0003fa624>] drm_framebuffer_remove+0xe4/0x128 [ 49.129171] [<ffffffc0003feaf8>] drm_mode_rmfb+0xc0/0x100 [ 49.135420] [<ffffffc0003efba8>] drm_ioctl+0x258/0x4d0 [ 49.140889] [<ffffffc0001b0388>] do_vfs_ioctl+0x338/0x5d0 [ 49.145921] [<ffffffc0001b06a8>] SyS_ioctl+0x88/0xa0 It makes no sense to free the ctl without disabling all stages, so lets just move them together to avoid the crash.
