I replaced my 13.04 install and with Debian wheezy, then unstable, but
didn't have any video hangs.

I then tried a clean install of 13.04 (as opposed to 12.10 then 13.04 as
before) and have had a couple of hangs. The first was a "soft hang"
where I could kill my desktop session by switching to a virtual console.
The rest have been hard machine hangs, the last one while I was on
youtube.

Title:
  Server hangs preceded by "EQ overflowing."

Status in X.org xf86-video-intel:
  New
Status in “xserver-xorg-video-intel” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to raring, my Lenovo Twist has begun to freeze and
  crash. Sometimes I am able to switch to vt1 to restart X, sometimes it
  just hangs hard. In all instances the behavior coincides with the "EQ
  overflowing" messages in Xorg.log. One saved X log contains:

  (EE) [mi] EQ overflowing.  Additional events will be discarded until existing 
events are processed.
