Don't we have a generic non-deterministic issue in the way geom  
providers are probed/detected/presented, e.g. if no *id provider is  
disabled, a ZFS array may present parts with gptid, some with diskid  
and so on? This would then be just another instance of this issue  
showing up.

Bye,
Alexander.
