:New submission from Edward O'Callaghan <eocallaghan at auroraux.org>:
:
:Each time the machine shuts down, dmesg throws a nasty looking message:
:
:Shutting down ACPI
:AcpiOsUnmapMemory : Warning, deallocation did not track allocation:
:0xda627f60/000000a0 (actual was 0xda628000/00000032)

:ver, 2.4.1 , i386, Lenovo X301.

:Regards,
:Edward.

    It is a bug in the BIOS's AML code.  It is attempting to unmap memory
    which it did not previously map.  If the machine still shutsdown ok
    you can ignore it.
