geom_vinum problems (crashes and lockups)

before i start, here is the ondisk config for both
drives used in the mirror volume:

mp3# dd if=/dev/ad4s1d skip=8 count=6 | tr -d

scenerio #1

the following, for me, ends up in a lockup (machine
freezes, can't do anything and i have to hard reset)

mp3# kldload geom_vinum
mp3# gvinum
gvinum -> list
2 drives:
D drive1                State: up       /dev/ad4      
 A: 0/29333 MB (0%)
D drive2                State: up       /dev/ad6      
 A: 0/29333 MB (0%)

1 volume:
V mp3                   State: up       Plexes:      
2 Size:         28 GB

2 plexes:
P mp3.p1              C State: down     Subdisks:    
1 Size:         28 GB
P mp3.p0              C State: up       Subdisks:    
1 Size:         28 GB

2 subdisks:
S mp3.p1.s0             State: stale    D: drive2     
 Size:         28 GB
S mp3.p0.s0             State: up       D: drive1     
 Size:         28 GB
gvinum -> stop

also, at the console (when i do the kldload) I get:
FOO:  sd mp3.p1.s0 is stale
FOO:  sd mp3.p0.s0 is up

Note: the entire time, the ssh session stays connected
and I can move around throughout the virtual shells
(alt+f#), but can't type on anything.

It responds to pings still, but won't serve any pages
(apache2).

scenerio #2 (I used to be able to do this just to get
some data copied to the volume and then rebuild it
afterwards).  When one volume is up (mp3.p0.s0) and
one is down (mp3.p0.s0) I get the following:

mp3# kldload geom_vinum
FOO:  sd mp3.p1.s0 is stale
FOO:  sd mp3.p0.s0 is up
mp3# fsck -y /dev/gvinum/mp3
fsck: Could not determine filesystem type
mp3#
mp3# fsck -y -t ufs /dev/gvinum/mp3
** /dev/gvinum/mp3

CANNOT READ BLK: 128
CONTINUE? yes

THE FOLLOWING DISK SECTORS COULD NOT BE READ: 128,
129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139,
140, 141, 142, 143,
ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: /dev/gvinum/mp3: can't read disk label
mp3#

So I figure, what the hell...lets mount it!

mp3# mount -t ufs /dev/gvinum/mp3 /usr/home/mp3
CRASH
FOO:  sd mp3.p1.s0 is stale
FOO:  sd mp3.p0.s0 is up

FOO:  sd mp3.p1.s0 is down

I can't get anymore info from the bt because I don't
seem to have a debug build of geom_vinum....and i'm
not sure how to build one.
