Ah ok. Hmm. Lukas will need to look at the initialization code path again
I think. Sounds like some random pointer is being used somewhere.

I use a third method: load geom_vinum.ko in /boot/loader.conf:

[stijn at sandcat] <~> cat /boot/loader.conf | grep geom_vinum
geom_vinum_load="YES"

But maybe those lost configurations have something to do with
disks/controllers as well? Mine are Promise Ultra133 with Maxtor
200/250G drives, as well as an internal IDE chipset with Maxtor 120G
drives.

In any case, that's really an area that I'm unable to help you with,
it all depends on a lot of GEOM internal stuff that I don't understand
(yet).

HTH,

It doesn't help. Almost all you ever get is "This mind intentionally left
blank."
