Hi,

My understanding of 'dist-upgrade' is that installs the new kernel NOT 
the latest system the command sudo do-release-upgrade -d is the one for 
that so you should be safe.

Of course the way I would try first is via synaptic and mark all the 
kernel packages (the new one!) for re-installation then reboot and see 
what happens, at least that way you have more control / visibility over 
what is going to happen.
Of course synaptic is no longer installed by default so if you haven't 
already you can install it with sudo apt-get install synaptic. Still 
find it more useful than the software centre (and yes I'm English so 
centre IS spelled corectly ;D)
Just my thoughts!
