Can you try reverting r265321 and see if you still see the
same crash?

I'll do the revert, but it's been a ONE TIME hit.

There was a followup to mine with a reproducible poudriere crash like mine.

If you don't have a reproducable senario I'd hold off.

Florian, is yours reproducable and can you send me
a pretty print of the crashing zio?


I think I may have hit the same problem; I'm going to stay connected to the 
console and see if it happens again; this is what I see currently with the

I just updated to I think 268921 earlier today and this is the first time I've 
had a panic (HEAD-268921 that is)

I'll try to get some more data if I can get it back up and running.
