Some updates on this... 'zpool import' shows the pool OK but when I try
to actually import it, I get the aforementioned panic. Under BeleniX I
cannot import it because it says the pool is corrupted. The
(crash) problem also occurs with 7.0 beta 2. So I cannot access an
otherwise healthy pool now. :-P

Now I got to examine the logs too. Right before the pool becoming
unaccessible, these log entries appeared:
