This issue is not fixed.

I have a eeebox b202 with an intel chipset. I am running XBMC on top of
ubuntu server. There is a 32' LCD screen plugged from the DVI output.

I installed the latest intel driver from the testing ppa as instructed.

After playing videos for a few minutes, the screen goes black (sometimes
gray or other colors) and on the X11 output I have those "underrun on
pipe a!" messages every second or so. Restarting X does not help.

The bug is exactly this one :
http://bugs.freedesktop.org/show_bug.cgi?id=18491

Strangely enough, it does not happen when I play a 720p video, only a
Small Definition one. Maybe an interpolation problem ?

I temporarily solved the issue by adding this to my xorg.conf :
Section "Device"
        Identifier "Configured Video Device"
        Option "FramebufferCompression" "false"
EndSection

There is a slight decrease in video performance (my system is a bit
borderline for 720p video) with those parameters so it would be nice if
the system could run full performance.
