vinum troubles

[Maxim Mazurok]

strange troubles....
i have panic if i run `vinum start` from singleuser mode.
i have panic if i put string `vinum_start="YES"` into rc.conf.
i don't have panic if i run `vinum start` after full boot of OS.
i try compilling kernel width `device vinum` or widhout.
i try `kldload vinum` before `vinum start`.
and have same results.

root at fang:~#uname -r
5.3-RELEASE-p4

next example - from console in singleuser mode:
