UFS2 (invalid format) boot problem

[Tomi Vainio - Sun Finland]

I've tried to migrate my system to use UFS2 on all file systems.
Creation, dump, disklabel done without problems I think because if I
use UFS1 on new root everything works using this same procedure.  When
using UFS2 I just get

"Invalid format"

FreeBSD/i386 boot
Default: 1:da(1,a)/kernel
boot:
No /kernel

Boot from old disk after this works also fine
3:da(3,a)/boot/loader

Any ideas?
