dmesg

During normal workload (multiple browsers, terminal, thunderbird), I see a few
second freeze, then both monitors turn black for an instance, then everthing
comes back and seems to work fine. There are some visual glitches in some
windows, but a redraw (move, resize) fixes that.

It happend a few times in less than an hour, but I do not know how to repoduce
the issue.

Did not happen with kernel 4.1, but I didn't test v4.2-rc1.

$ uname -a
Linux crux 4.2.0-rc2 #132 Mon Jul 13 21:13:09 CEST 2015 i686 i686 i686
GNU/Linux

Machine: Fujitsu Siemens Amilo M1450G

Monitors: laptop's own and one external connected via VGA

Attached the full dmesg, and I will upload a GPU crash dump soon.

Let me know if you need more information.
