That's sounds reasonable. A bit of explanation does wonders if I (or anyone else reading through the history *or* code) ever encounter similar bug reports. Is anyone else concerned by the acpi_lid_notifier never being decoupled when the module is unloaded? And the randomness of int_lvds_connector? I love our code, every time you read it you find another bug. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ dri-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/dri-devel
