On other archs GEOM works in old queued way. Somebody should port that small macro to other archs. But that is still interesting data point.

It may be specific to some GEOM class. Could you describe/show all GEOM topology, file systems, etc. you have there? gpart show sysctl kern.geom.confxml ... Thank you! -- Alexander Motin
