<pre>Sandybridge Desktop running Ubuntu 13.10 with the latest drm-intel-nightly
kernel from
<a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/">http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/</a> and
xserver-xorg-video-intel 2.99.904-0ubuntu2 drivers (latest in 13.10). I can
reliably reproduce this hang by going to maps.google.com in Google Chrome and
bringing up a complex page (I was using 311 W 34th St, New York, NY as the
test) and scrolling around, zooming out and zooming in. This does NOT cause
lockups on Firefox, only Google Chrome (not sure why). All Google Chrome flags
in about:flags are set to the defaults. Sometimes this causes the GPU to
hang, sometimes the entire PC is locked and must be hard-reset to fix (much
less likely but the last few times it happened, it's always been when I'm in
Google Maps on Chrome).</pre>
