Recently I've started to get Black Screen after some
hours of work at

    00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

It's a laptop+attached VGA to it.
I've gathered 2 erors states fo 2 such blackouts.

vanilla kernel:
linux-3.2.0-rc3-00099-g883381d

gentoo's userland:
xorg-1.11.2
libdrm-2.4.27
xf86-video-intel-2.17.0

Attached dmesg_1.txt for second dump, but there is nothing fancy.
The issue renders even without suspend/resume cycles. It just takes
a lot of time (0.5-2 days).

Thanks!
