Experianced a XOrg hang with a this message showing up DMESG.
Intel 2nd Generation Core 2 intel video (Intel(R) Pentium(R) CPU G850 @ 2.90GHz)
C200/H61 Chipset. (Onboard video)

Debug attached if someone wants to look at it.

Ubuntu 14.04

Linux kb3gtn-ham 3.13.0-39-generic #66-Ubuntu SMP Tue Oct 28 13:30:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

A switch to TTY0 and back to graphical mode seem to make it recover.
