Package: libdrm-intel1
Version: 2.4.9-1

Hello,

starting with 2.4.9-1 and up to 2.4.12-1 libdrm-intel1 crashes glxgears:
$ glxgears
Failed to initialize GEM.  Falling back to classic.
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
../../../libdrm/intel/intel_bufmgr_gem.c:689: Error preparing buffer map -1211144498 ((null)): Invalid argument .
glxgears: vbo/vbo_save_api.c:216: map_vertex_store: Assertion `vertex_store->buffer' failed.

Newer versions even dump a core. I found this on 2.4.12-1 first and
successively downgraded libdrm2 and libdrm-intel1 (and only them). The
problem persists down to 2.4.9-1. 2.4.5-2 was the first version where
glxgears did work:
$ glxgears
2429 frames in 5.0 seconds = 485.743 FPS

Other packages probably of interest:
$ COLUMNS=72 dpkg -l linux-image-2.6.30-1-686-bigmem xserver-xorg-video-intel libgl1-mesa-dri libgl1-mesa-glx libglu1-mesa mesa-utils | grep ^.i

GEM is properly supported by kernels in unstable, closing.
