Yesterday, I upgraded a system running 11.1-RELEASE to 11.2-RC1, but then hit a kernel panic during boot. The message on the screen disappeared so quickly that it was difficult to track down the cause. It turned out the problem was with VirtualBox kernel modules. The KBI is supposed to be stable between point releases, but apparently VirtualBox is special. Anyway, this caused me more time than I am willing to admit, so beware if you are running 11.2 and load VirtualBox kernel modules built on 11.1.
