In the kernel, I see such log entries: [drm:i915_gem_object_unbind] *ERROR* Attempting to unbind pinned buffer Xorg.0.log looks like this: (WW) intel(0): intel_uxa_prepare_access: bo map failed: Invalid argument (EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Invalid argument. This happens on a Mac mini Core Duo with i945 graphics. Any hints how to fix this? I tested some 2.6.37-rc kernels (rc3 to rc8) without having this issue. So it might be some upgrade of another component. I downgraded libdrm2 from 2.4.23 to 2.4.21, and restarted the X server, but it didn't help. Regards, Tino
