Guys,
I don't want to be rude but, Linux 3.13 sucks a lot.
I'm wondering here, for God's sake, why Ubuntu 14.04 comes with this lame kernel? What Ubuntu Kernel Team have in mind?!
Mark Shuttlework must say something about this situation. What he is gonna do? I really t want to know that.
I'm a HUGE fan of Ubuntu, and I mean it, I have no plans to switch off Ubuntu and I'll stick with 14.04 but, definitely, Linux 3.13 was a bad, bad choice for a LTS version like Trusty.
I'm facing a massive number of problems with this kernel, nights awake... And I'm not alone.

I just installed a lot of QEmu 2.0 Hypervisors with Trusty, including a brand new Cloud Computing with OpenStack IceHouse and, guess what?! Lots of problems... Because of Linux 3.13.
This is a unprecedented situation, Canonical must provide a new Kernel version for Trusty ASAP! This is affecting hundreds of people around the world that are trusting in Trusty but, it is not trustable right now. :-/
As a workaround, I backported the Kernel from Utopic, since I need the bnx2 kernel module (linux extra), I can not just use the mainline packages as-is...
