When running the good kernel you can remove the problematic kernel (and hope the next one will work better for you, when it arrives). Double check to be sure to remove the bad one and keep the good one!

sudo apt-get remove linux-image-xxxxx

where xxxxx is the identification of the problematic kernel (maybe 3.11.0-24-generic)

Might I add, use Software Updater to update the system.

Reboot and after the BIOS screen press shift. This should get you to a menu with all installed kernels. Select and boot the good kernel. In a terminal, run:

uname -r

That will tell you which kernel you are using. I use Synaptics, but probably this can be done in SCentre: search for 'linux image' and delete the ones you don't want.

Always a good idea to keep the one you are using and the one before it. BE CAREFUL NOT to remove the kernel you are using! ;)

PS: Your 'udio' is missing? What is that? I'd personally leave things as they are and just choose the kernel you want at boot. Boot into and update the new kernel in a week and try it again. Removing it directly after install is fairly drastic. These things sometimes take time to mature ...
