I was scrolling in gvim on Thinkpad x220 and everything became slow. New X
windows are completely black. It happened only 1 time so far but I upgraded to
the kernel to 3.16-rc6-amd64 (from Debian packages) only yesterday. It looks
similar to <a class="bz_bug_link

[22130.610628] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.

against DRI -> DRM/Intel

component if it's not a kernel issue.
[22130.610635] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
