Yes. And the correct kernel (i.e., the 9.2 kernel) is the one that did not see the MBR on ada0. > > > /dev/ad0 /dev/da0s1a /dev/da3 > > /dev/ad0s1 /dev/da0s1d /dev/da4 > > 9.2 should look for /dev/ada0 etc. 9.2 should also create symlinks for /dev/ad0* to the /dev/ada0* nodes. > > It might be necessary to edit /etc/fstab before rebooting. As I wrote before, I tried it both ways. It really doesn't matter if it can't see the MBR and therefore never creates nodes or symlinks for the slices and partitions. All it had was /dev/ada0. I suppose it may have created a symlink named /dev/ad0, but the mountroot prompt didn't show any symlinks, so I have no way of knowing. > > I only installed 9.2 once but did not face any problems with MBR. > Did your boot drive have a MBR on it?
