So I'll bet there's more than just those messages in dmesg. In any case, please try out the latest upstream driver sources first for mesa (9.1 branch) and kernel (3.8-rc series) to ensure it's not a know bug. If it still hangs you /should/ get a line about i915_error_state in debugfs in dmesg. Please file a bug report on bugs.freedesktop.org with that file attached (and citing all the git versions you've used for testing). -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
