[First I reported this problem over a week ago on the intel-gfx mailing list,
but I got neither a bounce nor did the email ever appear. If you plan to run
your mailing list for some private cabal only please mark them so that people
do not waste time with them. Thanks]


The current version of chrome reproducibly hangs the GPU on my
sandy bridge system when using google maps. The GUI freezes
and I have to kill chrome from a console to recover.

Known problem? Crash dump is attached.

Kernel 3.15.1 (opensuse version)

[522626.357015] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
[522626.357016] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
[522626.357016] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[522626.357016] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
