Sorry I'm also late for this review. I guess this means the backport I made for the 3.5 kernel (and released on 3.5.7.26) is incorrect: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=commitdiff;h=745545489d25d1b9ecf2d78a8f9a31a362806d2d Akira, could you please confirm if this is the case so that I revert it in next release?
