The problem is not gma_backlight_init but rather psb_modeset_init that calls the errata for the chip that in turn sets the brightness before any initialization is done. Commenting out the call to dev_priv->ops->errata in framebuffer.c makes boot get to the end like it used to on 3.4. It seems to be just an ordering problem in the end. -- mattia :wq! _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
