--- Comment #1 from Dennis Clarke <dcla...@blastwave.org> ---
I tried to push this a little further and could not get a panic again.
Once is usually enough.
However I did add some more devices to the zpool and tried to toss
some activity at it. No panic seen on a reboot.

Did a shutdown and then boot. No problem seen.
Really a full fresh build is needed.
