/sys/class/drm/card0/error

X was frozen for a short moment and I got the following messages in dmesg:

[29637.380428] perf interrupt took too long (5015 > 5000), lowering kernel.perf_event_max_sample_rate to 25000
[30661.816011] [drm] stuck on render ring
[30661.817275] [drm] GPU HANG: ecode 0:0xfdffffff, in Xorg [2173], reason: Ring hung, action: reset
[30661.817280] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[30661.817282] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[30661.817283] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[30661.817285] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[30661.817289] [drm] GPU crash dump saved to /sys/class/drm/card0/error

Looks like vertex data overwrote the batch. Can you please make sure you have the latest ddx (driver for Xorg) and attach your Xorg.0.log.

Hmm, .914, ppa:xorg-edgers should have a .917 very soon.
Comment 4 Lars Ljung 2014-12-21 20:48:13 UTC 
I'll try it, thanks.
Comment 5 Ander Conselvan de Oliveira 2015-06-25 12:28:52 UTC 
Closing due to inactivity. Please reopen if you can reproduce the issue with an updated ddx (driver for Xorg).
