Comment 2 Len Brown 2004-02-18 18:40:56 UTC

    ACPI-0279: *** Error: Looking up [BUFF] in namespace, AE_ALREADY_EXISTS
    ACPI-1120: *** Error: Method execution failed [\_SB_.BAT1._BST] (Node 
cee8e740), AE_ALREADY_EXISTS

please try 2.6.3 -- we fixed an ACPI parameter issue that may help this.
also, did any previous releases work?

thanks,
