GPU crash dump, taken from /sys/class/drm/card0/error
Can you please try to reproduce this with the latest drm-intel-nightly kernel? (In reply to Ben Widawsky from comment #2) > Can you please try to reproduce this with the latest drm-intel-nightly > kernel? I guess not. Timeout, closing. Please reopen if the problem persists with latest kernels. Yes, sorry, I don't have this laptop anymore. Yes, the problem still persists. We don't have batch level granularity in our reset, therefore when one component hangs the GPU all pending rendering is lost and other clients suffer corruption.

Is this an enhancement you want to track in bugzilla? |

Created attachment 104805 [details] Screenshot of font corruption I sometimes notice a short interruption where the system is not responsive. After a few seconds, it's usable again, but graphics in opened windows like the browser is corrupted (most times, only single font characters are corrupted, for instance all "9" are replaced by "e" - this is not a single rendering issue but persists and can even be captured by a screenshot, see attached screenshot). dmesg shows: [ 3738.273393] [drm] stuck on render ring [ 3738.273403] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 3738.273404] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 3738.273405] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 3738.273406] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 3738.273407] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
