amd... My 2 amd systems panic with vinum start but the P4 works ok built
from the same sources.  All with no vinum volumes, just trying vinum
start t test for this bug.

Ok, then I think I know what it is.

Vinum appearantly does not go through SPECFS but rather calls into
the disk device drivers directly.  That is a pretty wrong thing to
do, and it seems that vinum does not respect the D_NOGIANT
flag which GEOM recently started setting.
