Upgrading VirtualBox causes instability

I'm going to reboot, but things went boom

reinstalling toolbox didn't work - I ended up having to uninstall vbox and re-installing after that.

looks like the vboxdriver failed to be there dur to upgrading vbox 5.0.12 to 5.0.14 - very odd.

Re-labeled this as I've seen many cases where upgrading VirtualBox causes instability
