"[mi] EQ overflowing." on Nexus 7 - Xorg frozen

[Jean-Baptiste Lallement]

While running browsing tests (https://wiki.ubuntu.com/Nexus7/BrowsingSimulation), for the 3rd time in a row, X suddenly stopped responding and the display of the device froze.

The device is still alive though and usable through ssh.
