Just got a panic on 9-stable, running inside VirtualBox, trying to
build a release-set. Don't know yet if reproducable, just happened a
few minutes ago.
The whole core.txt stuff follows below (beware of line-breaks):

According to the above, your ada1 "virtual disk" fell off the bus
entirely. Relevant storage bits taken from your dmesg:

My recommendation is to remove VirtualBox from the picture entirely and
instead do whatever you were doing (running zfstest) on bare metal.
Yeah, would love to.
But http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/155587 prevents me
from doing so. I'm trying to build a live-disc that includes
http://svnweb.freebsd.org/base?view=revision&revision=226617 so I can
recover the pool.
