The GPU gave up. That's a pattern I attribute to media hangs, so I would expect this to be userspace. I haven't seen these since. If they keep away for a week more, I'll mark this as WORKSFORME. (There are occasional recoverable GPU hangs in random 3D programs, but I'm not filing bugs on those until they repeat. This I filed just because there were so many hangs on the same test run.) Only issues I see on KBL GT3e is bug 111424 with Mesa, I haven't seen this issue since => marking as WORKSFORME. |

Created attachment 145095 [details] KBL GT3e i915 error state Setup: * HW: KBL GT3e * kernel: drm-tip git v5.2 kernel * OS: Ubuntu 18.04 * Desktop: lightdm/Unity/compiz * Latest MediaSDK & FFmpeg built from Git Use-case: * Run many parallel video encode tasks in parallel, first using FFmpeg with VA-API backend, then using MSDK sample_multi_transcode application Expected output: * No hangs Actual output: * Last number of (recoverable) GPU hangs on rsc0 (media-driver uses compute EUs to do some of the transcoding operations) Notes: * This may be media driver issue, but media driver (Github) tracker doesn't allow attachments like i915 error state, so I though better to start from here
