No, they where configured.
I have one ' d: 17848151       63     vinum    ' slice per drive.
The only fault where the misspelling of 'stripe' versus 'striped' in the 
configfile!

Hmm, strange - see my above comment regarding the drive configuration.

The same disks, the same configfile (but with proper spelled 'striped':

# cat x
drive d1 device /dev/da1d
drive d2 device /dev/da2d
volume raid
 plex org striped 256k
  sd length 50m drive d1
  sd length 50m drive d2
# vinum create x
Configuration summary

Drives:         2 (4 configured)
Volumes:        1 (4 configured)
Plexes:         1 (8 configured)
Subdisks:       2 (16 configured)

D d1                    State: up       Device /dev/da1d        Avail: 8664/8714

D d2                    State: up       Device /dev/da2d        Avail: 8664/8714
MB (99%)

V raid                  State: up       Plexes:       1 Size:        100 MB

P raid.p0             S State: up       Subdisks:     2 Size:        100 MB

S raid.p0.s0            State: up       PO:        0  B Size:         50 MB
S raid.p0.s1            State: up       PO:      256 kB Size:         50 MB  

The panic occurs only, if I first use the incorrect config file with 'stripe',
then the corrected one with 'striped' and then detaching the plex and the 
subdisks.
BTW: It should'n panic in any case.

I haven't set up remote debugging.

Sorry, its behind a firewall which I can't manipulate and it blocks telnet and
ssh at the moment.
But I'm shure you can reproduce the panic by following the steps I have taken.
