<div dir="ltr"><div>Hi, <br></div><div><div> </div><div>I have an intermittent deadlock/hang in the amdgpu driver. It seems to happen when I open a new tab in qutebrowser(v1.1.1), while I am doing other stuff, like watching youtube through mpv or playing dota 2. It seems to be pretty arbitrary how often it happens. Sometimes it is once a week and sometimes multiple times a day. I have a vega 64. </div><div> </div><div>What happens is that the screen freezes but I still hear sound and can ssh in to the box. If I reboot it remotely, I get dropped back to tty and it tries to reboot but it gets stuck on blocking processes(mpv etc) so I have to reset it manually. </div><div>Repro steps: </div><div> </div><div>* run qutebrowser </div><div>* Do a bunch of other stuff, videos, games etc </div><div>* Switch back to qutebrowser and hit "Ctrl+t" & be "lucky" </div><div> </div><div>This seems to happen on all release candidates for 4.15 and 4.15 itself: </div><div> </div><div>4.15:</div></div><div><div>[ 2211.463021] INFO: task amdgpu_cs:0:1053 blocked for more than 120 seconds. </div><div>[ 2211.463026] Not tainted 4.15.0-ARCH+ #1</div><div>[ 2211.463028] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. </div><div>[ 2211.463030] amdgpu_cs:0 D 0 1053 1051 0x00000000 </div><div>[ 2211.463032] Call Trace: </div><div>[ 2211.463040] ? __schedule+0x297/0x8b0 </div><div>[ 2211.463043] schedule+0x2f/0x90 </div><div>[ 2211.463045] schedule_timeout+0x1fd/0x3a0 </div><div>[ 2211.463085] ? amdgpu_job_alloc+0x37/0xc0 [amdgpu] </div><div>[ 2211.463088] dma_fence_default_wait+0x1cc/0x270 </div><div>[ 2211.463090] ? dma_fence_release+0xa0/0xa0 </div><div>[ 2211.463092] dma_fence_wait_timeout+0x39/0x110 </div><div>[ 2211.463119] amdgpu_ctx_wait_prev_fence+0x46/0x80 [amdgpu] </div><div>[ 2211.463145] amdgpu_cs_ioctl+0x98/0x1ac0 [amdgpu] </div><div>[ 2211.463149] ? dequeue_entity+0xdc/0x460 </div><div>[ 2211.463174] ? amdgpu_cs_find_mapping+0xc0/0xc0 [amdgpu] </div><div>[ 2211.463185] drm_ioctl_kernel+0x5b/0xb0 [drm] </div><div>[ 2211.463194] drm_ioctl+0x2ae/0x350 [drm] </div><div>[ 2211.463218] ? amdgpu_cs_find_mapping+0xc0/0xc0 [amdgpu] </div><div>[ 2211.463239] amdgpu_drm_ioctl+0x49/0x80 [amdgpu] </div><div>[ 2211.463243] do_vfs_ioctl+0xa4/0x630 </div><div>[ 2211.463246] ?
