    That'd be great. HP's bureaucracy makes it hard for me to borrow
    machines. If you could also turn on CONFIG_PNP_DEBUG_MESSAGES
    and boot with "pnp.debug", we should get some clues about what _CRS
    returns for all the ACPI devices. Just attach the resulting dmesg
    to the bugzilla (http://bugzilla.kernel.org/show_bug.cgi?id=14183).
