vinum drives crash in 5.2.1 but work in 4.9

I have a rather large (ok, I'm insane, its that large) Vinum array,
which works fine in 4.9, but crashes in 5.2.1.  I don't think its
vinum's fault, but I could be wrong.

My question is: any ideas as to why the drives crash when accessed and
can't be labeled (other than my boot drive) in 5.2.1, but work fine in

More info about my setup follows:

The array works, mounts, I can read/write to it and everything in 4.9
just fine, but when I try it in 5.2.1, it crashes when it tries to
access the disks. (btw, everything is backed up and I can wipe these
drives if need be).

I'm trying to get this to work in 5.x because Samba 3 needs 5.x for some
features to work.

Anyway, when I typed "vinum start" at the root prompt in 5.2.1 I got the
following panic:

Fatal trap 18: interger divide fault while in kernel mode
cpuid = 0; apic id = 00

when i rebooted and just typed "vinum" at the root prompt, the following
is the output I captured while I was ssh'd into the machine:

[etc... snipped because this is getting really long.  basically all the
subdisks associated with the "down"'s changed to "crashed"]

vinum -> stop
vinum unloaded

So not sure what to do next, I tried to look at some of the disk's
# bsdlabel ad4s1

bsdlabel: /dev/ad4s1 read: Input/output error

but when I look at my boot drive:
# bsdlabel ad0s1
