Vinum raid5 problems......

Hi all:

I have a FBSD 5.2.1 box running vinum.  7 *160gb drives in a raid5 array.

The array has been problematic recently, but never anything too serious.
  Always recoverable by a rebuild or something of that nature.

Two days ago, the box froze up.  I brought it back online to see that
one subdisk was down.  I started it and it regenerated overnight without
error.

Today, i go to check the box over, a listing of vinum subdisks & plexes
looks exactly as it should.

when I try to mount the raid5 partition, i get a message about being
unmounted improperly and an fsck starts.  It says it recalculated the
superblock, completes, and mounts the raid5 partition.

df -h shows the partition size correct, but the used and freespace are
completely wrong.

If I try to do  fsck_ufs /dev/vinum/raid5, i get an error....cannot
allocate xxxxxx bytes for inphead.

If I try to read from the partition, i cause a kernel panic.

I can post specific errors and logs and such later, i'm away from the
box right now --- anybody have any thoughts ?
