sorry I should be clearer.
the problem that alexander' patch fixes, does not exist in 3.9-rc1
because the problem is fixed by this commit
b8bb6cb999858043489c1ddef08eed2127559169.

so what we need is, either 3.8.x kernel + alexander's patch, or clean
3.9-rc1.

then I'll back port b8bb6cb999858043489c1ddef08eed2127559169 for 3.8
stable.
