gmirror+gjournal: unable to boot after crash

Hi,

after one month with gmirror and gjournal running on a 7.0-RELEASE #p2 amd64 (built from latest CVS source), the box hung a couple of times when on high disk load. Finally, while building some port it won't boot for no reason obvious to me.

This is what I get with kernel.geom.mirror.debug=2:

The 3rd boot loader lists directories.

Any idea how this could be fixed via a remote serial line? Any chance to boot this without GEOM?

Best regards.
