I've just found and fixed a bug in Vinum which can cause the system to
crash on start.  It didn't exist in 3.2, and is fixed in 3.3-STABLE.
Briefly, 3.3 now allows you to put Vinum drives on any partition on
any slice, and it checks these slices on start.  If you don't have any
slice entries (/dev/da0s1a and friends), however, it will panic after
(incorrectly) reporting some subdisks to be crashed.  This bug does
not cause data corruption.

This bug has been fixed in 3.3-STABLE.  A copy of the kld is available
at ftp://ftp.lemis.com/pub/vinum/vinum.ko-3.3-STABLE-30Sep1999.

Note also that when upgrading from FreeBSD 3.2 to FreeBSD 3.3, you
must ensure that your Vinum drives are of type Vinum.  disklabel(8)
should show:

     3 partitions:
     #        size   offset    fstype   [fsize bsize bps/cpg]
       a:  2048000        0     vinum                        # (Cyl.    0 - 1042)
       c:  2048000        0    unused        0     0         # (Cyl.    0 - 1042)

If your partition is of type 'unused', change it with 'disklabel -e'.
