vinum: page fault panic in vn_strategy

[Rumko]

I have 2 disks that I was preparing for a vinum based raid1 mount and some time
ago were mountable (just not as root mounts :) ), but now when I start vinum,
the mentioned panic occurs. Not quite sure, but I think the vinum config I
used for the disks is the one at http://www.rumko.net/dragonfly/config and the
disks are labelled like http://www.rumko.net/dragonfly/disklabel

The dump is at leaf:~rumko/crash/vinum/*
Unread portion of the kernel message buffer:
<6>vinum: loaded
