Intel video driver (855GM etc) support is broken in Debian (linux-tree-2.6 v2.6.12-1, xserver-xorg v6.8.2.dfsg.1-4) at the moment. That's the i810 Xserver driver using the i915 kernel drm module.
After a suspend/resume cycle, any OpenGL programs fail, e.g. $ glxgears intelWaitIrq: drmI830IrqWait: -16 A message appears in dmesg: [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY -- rec: 4229 emitted: 4239 This is a known bug, reported at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=159960 and https://bugzilla.ubuntu.com/show_bug.cgi?id=7787 and http://www.mail-archive.com/[email protected]/msg21138.html A patch has apparently been made to X.org CVS, so we'd need to check it has been applied in Debian's copy of 6.8.2 (Daniel Stone has apparently applied it to Ubuntu). A kernel patch to i915 is also needed (provided by dri.freedesktop.org, exact urls mentioned in the Redhat bug report). I don't know if it's Debian's X.org or 2.6.12 kernel, or both, which needs the patches, so I'm not filing a bug till we know.
