Hi,

I kept the thread of "Hardware Enablement Stack notice?", but changed the
subject, since this is a hint for the thread with the subject
"Upgrading to 16.04", too. 

Even if modules build without trouble, vbox has tendencies to cause
issues, be careful.

You should take a look at the bug tracker and forums, search for your
Ubuntu release, your vbox version, your kernel version, your qt
version, what guests are running, your cpu etc., for example
