The hang does not occur when the power state is set to low. There are also no rendering glitches (otherwise some frames seem to have random triangles on them). |
Created attachment 218111 [details] Stack trace (sysrq-w) This happens after a few minutes in a 3D-intensive workload (e.g. Kerbal Space Program). The game hangs, but the mouse is moving. A few seconds later the mouse stops moving. 1. The game is waiting on an ioctl (libdrm: amdgpu_fence_wait/amdgpu_cs_query_fence_status) 2. Xorg is in D state (see attached stack trace). 3. CPU load at ~0%. 4. Nothing interesting in kernel log. The kernel has voluntary preemption enabled, the GPU is 1002:6938 (AMD Radeon 380X). It is at 56°C, quickly drops down to 51 when forced to low performance state, goes up to 56 when at auto.
