If GPU blacklist is disabled in Chromium (on chrome://flags; so hardware
accelerated rendering become enabled, judging from chrome://gpu) GPU sometimes
lockup on just opening new tab (at least one time per day). After lockup I
observe same behaviour like in <a class="bz_bug_link
bz_status_NEW "
title="NEW --- - [RV635] when GPU locks up, reset happens but X is unresponsive except mouse"
href="show_bug.cgi?id=77892">Bug 77892</a> - reset happens but X is unresponsive
except mouse.
Radeon HD 6620G, Kubuntu 14.04 x86_64, Linux 3.15rc3, X.Org Server 1.15.1,
libdrm 2.4.54+git1405030630.5126fc, Mesa 10.3~git1405030730.64c467, radeon
driver 7.3.99+git1405030730.be1469.
As I remember, this behaviour (GPU hang on opening new tab) introduced since
Linux 3.15.</pre>
