panic: no init

[Eugene M. Zheganin]

Hi.

I'm using FreeBSD as a desktop. When updating from r251990 to a higher
revision (both GENERIC kernels) I got 'panic: no init' message after
mountroot (I'm using zfs, seems like mountroot was successful). Nothing
changed in my configuration, so I have totally no clue. Right now I'm
running r251990 kernel on a newer world. How can I get rid of this panic
and run newer kernel ?

Thanks.
Eugene.
