Okay, I did a bisection and was not able to correlate the above error 
message with the problem I'm seeing. Not saying it's not related, but I 
had plenty of successful test runs in the presence of that error.

Took me about a week (sometimes it takes as much as 6 hours to produce 
the error), but bisect narrowed it down to this commit:

http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=9a727a813e9b25003e433b3dc3fa47e621f9e238

What do you think?

Thanks!
