Uff, really don't know what to say, when I thought I saw some light... 
I've been testing with 2.6.31-rc6 and 2.6.31 (final) with and without 
patches and maybe is only the probe_mask option what make it work sometimes.

Perhaps I did bisect bad and wasn't 
deadff1665491afce124a8ff83f00f784161f660 first bad commit?
