Created attachment 93892 [details] GPU crash dump Judging from dmesg, I got a GPU hang and I'm expected to file a bug. $ uname -a Linux beevvy-n02 3.13.2-gentoo #1 SMP PREEMPT Sat Feb 8 19:19:27 CET 2014 x86_64 Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz GenuineIntel GNU/Linux Mesa version: 9.2.5 # dmesg|grep '\[drm\]' [ 0.439376] [drm] Initialized drm 1.1.0 20060810 [ 0.440323] [drm] Memory usable by graphics device = 2048M [ 0.476502] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

What was I doing: I just booted the machine, logged in (I'm using KDE 4.12.2, with KWin), run Firefox and browsed the web, nothing fancy, no WebGL. And then it happened.
