Remove any package with generic in it's name. (should be 3):
linux-image-3.5.0-33-generic, linux-headers-3.5.0-33-generic and
linux-image-extra-3.5.0-33-generic.

You may also want to remove (if they are installed):
linux-generic, linux-headers-generic, linux-image-generic, linux, linux
image, etc. I can't remember which ones the upgrader uses to point to the
latest generic kernel. However, if you leave them installed, they may pull
in the next new generic kernel again.

They don't. The upgrader is not a UbuntuStudio Project and seems to break
some things in UbuntuStudio. A fresh install just has the low latency
kernel... at least any of the UbuntuStudio versions I have tried ... all
of them from 12.04 to 13.10alpha. I, personally, have had other issues
with upgrades in Ubuntu Studio as well. Reinstall is best. (but then I
have been doing fresh installs since SlackWare 0.9.* or so... maybe I
should come out of the dark ages?)
