What version of mesa does your libdri come from?
Ensure that xorg-server, mesa and xf86-video-intel are all built against the same version of libdrm. Please also describe the circumstances in which this happens.
segfaults usually happen during a) desktop startup/initialization with KDE and b) on return to X (i.e. alt-f7) after switching to text console all mentioned packages have been rebuilt with current versions over the weekend. segmentation fault occurs on startup once every few times and the desktop is fragile with GPU errors and render errors. graphic rendering is incredibly messy with a lot of blocks drawn in the wrong place and often the screen is shifted horizontally. moving objects leaves artifacts everywhere with a failed redraw once positioned. you have to guess where the buttons for dialogs are to attempt to click the right one. gentoo-sources 2.6.34-gentoo-r2 xorg-server 1.8.2 xf86-video-intel 2.12.0 media-libs/mesa 7.8.2 kde-* 4.4.5 GPU error is usually... (EE) intel(0): Detected a hung GPU, disabling acceleration
Can you still reproduce with newer versions? If so, please file a bug upstream [1] and paste the URL here so we can track the problem. Thanks [1] http://intellinuxgraphics.org/how_to_report_bug.html
