I think I was seeing the same panic in 2006... http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2006-12/msg00344.html Can you add this to src/sys/dev/drm/i915_irq.c if (!dev->irqr) { return DRM_ERR(EINVAL); } just above the DRM_WAIT_ON in i915_driver_vblank_wait() (around line 140), and see if that prevents the panic? Note that I believe this to be a workaround, and not really the correct fix. (sorry for not supplying patches, I'm not in a position to right now) Gavin
