It looks like e1000 might be being spit out. From what I gather in your
message, the only thing that changed was you are now putting a much
higher I/O demand on the drives (rsyncing everything), by extension this
increases the demand on the NIC.

If the e1000 nic is the one enslaved to the bridge, it could be clean up
that's making it freak when a guest stops. If its ejected uncleanly, the
PID next in line with pending i/o for the device will likely be
identified as the culprit.

I had a very similar problem with a buggy Areca driver on dom-0 a couple
of years ago.

Can you post a link to your kernel's .config, or perhaps try the latest
stable version of that module from:

http://sourceforge.net/project/showfiles.php?group_id=42302

As for ipv6, if its being set up you'll see it in /etc/sysconfig
or /etc/network (depending on the distro) pretty clearly. However, that
shouldn't make a difference .. it should work either way.

Hope this helps :)


Cheers!
