Is Linux 3.13, the worst kernel version, ever? YES! It is... So, why Trust come with it? WHY!?

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.
List of problems:
linux-image-3.13.0-29-generic - soft lockup in kvm guests:
guest hang due to missing clock interrupt:
[Supermicro X9DR3-F] Virtual machines hang in kernel 3.13:
KVM guests getting slow by time (Linux 3.13.0-29-generic x86_64):
Filled by myself - Ubuntu 14.04 + QEmu 2.0 + KSM = 1, makes Windows 2008 R2
guests to crash (BSOD):
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
Manually backporting Utopic's Kernel into Trusty:
1- Add the following line to your Trusty's /etc/apt/sources.list:
deb-src http://us.archive.ubuntu.com/ubuntu/ utopic main restricted
apt-get install fakeroot
apt-get build-dep linux
mkdir linux/source -p
apt-get source linux
dpkg-buildpackage -rfakeroot -uc -us
3- Install Linux via "dpkg -i linux..."
IMPORTANT NOTE: I still did not tested this Linux 3.16 from Utopic on
Trusty but, at this point, anything is better than Linux 3.13. I know that
my environment is terrible with 3.13 and I'll report here if it becomes
better with Linux 3.16.
Again, Canonical, please, say something about this.
As I said, I'm a huge fan of Ubuntu and I'm waiting to see what Canonical
will do about this.... Canonical, your turn.
