--- Comment #2 from Felice Tufo (info@felicetufo.com) --- Thanks Alex, it seems that Linus merged those patches (just today) for the next -rc release, am I right? If so, I'll do a quick test and let you know as soon as Ubuntu team will release the next mainline kernel (usually just 1 or 2 days after -rc is out).
