Log file with errors

I am running Arch Linux i686 on a Dell Inspiron 1525 laptop with an Intel
Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev
0c)

As you might know, Arch is a rolling distro with the latest software. A recent
upgrade of the installed packages made my display stay dark when I boot the
system. 

The logfile has at Jun 28 17:07:43:
GPU HANG: ecode -1:0x00000000, reason: Command parser error, iir 0x00008000,
action: continue

and

i915: render error detected, EIR: 0x00000010

One of these packages causes this: intel-dri-10.2.2-1  linux-3.15.2-1 
mesa-10.2.2-1  mesa-libgl-10.2.2-1  xf86-video-intel-2.99.912-1

Unfortunately I cannot provide a /sys/class/drm/card0/error, because my display
is not working at all. In order to make the laptop boot again, I have to boot a
rescue system and downgrade the installed packages with pacman -U
intel-dri-10.1.4-1-i686.pkg.tar.xz xf86-video-intel-2.99.911-2-i686.pkg.tar.xz
mesa-10.1.4-1-i686.pkg.tar.xz mesa-libgl-10.1.4-1-i686.pkg.tar.xz
linux-3.14.5-1-i686.pkg.tar.xz

Please let me know, if I can provide more info or do testing of any kind.

Thank you very much.
