With gmirror.patch I don't see the geom_mirror error messages, but then
it doesn't finish booting:

#######################################################
GEOM_MIRROR: Device gm0 created (id=861616013)
GEOM_MIRROR: Device gm0: provider ad0 detected
GEOM_MIRROR: Device gm0: provider ad2 detected
Mounting root from ufs:/dev/mirror/gm0s1a
setrootbyname failed
Root mount failed: 6
Manual root filesystem specification

So how do I go from here? Is there something else I can try?
