In the long term it can't be set, for the same reason _OS(Linux) can't be enabled -- it tends to confuse BIOS that are not properly validated with Linux. Further, the semantics and version information of _OSI(Linux) were never actually defined. The kernel prints out a message if it sees _OSI(Linux) requested, and there is a DMI workaround to invoke "osi=Linux" automatically for existing systems that need it. http://bugzilla.kernel.org/show_bug.cgi?id=7787 Signed-off-by: Len Brown --- Reading git-diff-tree failed
