Comment # 8 on bug 939622 from Darren Freeman

> What kind of dependency problem...?  The kernel should have little dependency, if any.

I forget, sorry. It got really messy, I tried updating a lot of packages at
once, and trying to add the newer kernel and remove the older one caused a lot
of dependency issues. So I decided to upgrade everything else, then do the
kernel.

Also I had to uninstall VirtualBox from OBS, and install it from
virtualbox.org, because the one from OBS doesn't know how to recompile the
kernel module against the new kernel.

I'm now on 4.1.x and I'll see how it goes.
