Nothing has changed. SNB can still randomly hard lock with rc6 and
vsync.

Title:
[snb] random hard lockup whilst using Xv
Status in X.org xf86-video-intel:
Incomplete
Status in “xserver-xorg-video-intel” package in Ubuntu:
Confirmed
Bug description:
When using the system for some time, at some point display freezes. The
system seems to continue working as mplayer remains streaming internet radio
and also the audio output works properly. During this lock-up the mouse can be
moved but any click is ignored. Furthermore any attempt to switch to a TTY is
ignored as well. Even worse the power button does not trigger a shutdown.
Therefore I usually hard reset by pressing the power button for several seconds.
I first witnessed this bug after upgrading to 13.04 (from 12.04). To make
sure, I freshly installed Ubuntu, but unfortunately this did not help avoing
the bug.
