https://bugzilla.kernel.org/show_bug.cgi?id=216224 Bug ID: 216224 Summary: AMDGPU fails to reset RX 480 after Ring GFX timeout Product: Drivers Version: 2.5 Kernel Version: 5.18.0 and earlier versions Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: happysmash27@xxxxxxxxxxxxxx Regression: No Created attachment 301374 --> https://bugzilla.kernel.org/attachment.cgi?id=301374&action=edit SteamTV-induced crash 2022-07-08 This is perhaps the worst bug I have ever experienced and has been going on for a couple years now. A ring GFX timeout can be triggered fairly reliably by launching SteamVR while using literally anything else that uses the GPU (even having Waterfox open usually causes a crash) or by running an Ethereum miner (every one I have tried does this, some worse than others) and having something else using the GPU such as Blender (moving around in a 3D scene should do it). Other things do this as well (such as the time this happened when running Sway and LXDE at the same time) but Ethereum miners and SteamVR seem to be the programs that trigger it the most reliably. I imagine trying to run both at once would be a guaranteed GPU meltdown. When the bug occurs, something like: [1767311.339261] [drm:amdgpu_job_timedout] *ERROR* ring comp_1.0.0 timeout, signaled seq=23354655, emitted seq=23354657 [1767311.339274] [drm:amdgpu_job_timedout] *ERROR* Process information: process vrcompositor pid 7701 thread vrcompositor pid 7701 [1767311.339279] amdgpu 0000:03:00.0: amdgpu: GPU reset begin! or: 57492.984178] [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout, signaled seq=9450226, emitted seq=9450228 [57492.984189] [drm:amdgpu_job_timedout] *ERROR* Process information: process vrcompositor pid 8198 thread vrcompositor pid 8198 [57492.984194] amdgpu 0000:03:00.0: amdgpu: GPU reset begin! or: [112094.633679] [drm:dm_vblank_get_counter] *ERROR* dc_stream_state is NULL for crtc '2'!

If frozen, cat cannot be killed with signal 2 or signal 9, as it will be in a d state. Furthermore, X and sometimes vrcompositor cannot be killed with it either as they will also be in d states. Shutdown will do nothing, so the only way to reboot is to manually shut down all processes then use the magic sysrq sequence to shut down everything. In one instance even that didn't work and I needed to hold the power key. SSH works fine as in other bugs related to ring GFX timeout. The subject of this bug isn't the ring GFX timeout itself, but the fact that the GPU reset never works. It's worked a couple of times (after manually restarting X from SSH of course), but 90% of the time it hangs and does not reset successfully. I will attach several dmesg (with color) logs from the several times this has happened in the past couple months, but if needed I have logs going all the way back to February 2020 as well. -- You may reply to this email to add a comment.
