gmirror on boot device after upgrade from 5.4 to 6.0?

[James Snow]

I have a 5.4-S machine on which I'd been running gmirror for some time
without issue. After updating to 6.0, I'm not able to boot properly at
all. Panics here and there depending on what I do trying to boot.

I'm skipping on detail for the time being because I just want to know:
Is there something I was supposed to do when updating the kernel for
geom_mirror to continue to be bootable?
