Then I can't take this patch at all in any stable tree. Please read Documentation/stable_kernel_rules.txt for why and how to properly do this. Just mark the commit that fixes the issue in Linus's tree for stable, and it will happen automatically. > The back port of the fix commit will have many dependencies as we have > a big change in ACPICA table manager in ACPICA 201403xx release. Why not just submit this fix first to Linus, for his tree now, and then do the larger changes later? > However this back port is very light and has been confirmed by the reporters. > > The bug seems to be urgent, it has broken many platforms shipped with > AMI BIOSes versioning from F2 to F4.
