If you have compiled the xen kernels in their own directory (that is 
generated when unpacking the sources), the compiler should not have 
taken any other config. And you would not have a xen kernel if it was 
the vanilla kernel config.
Okay, nothing you have setup on your own.

Then I would  carry the problem over to the developpers mailing list, 
maybe open up a bug report. Before that you could test it with Xen 3.0.2 
and kernel 2.6.16 (to see if it has been solved inbetween).
If you want to find out on your own, you have to compare the contents of 
your routing table, nat table etc. before and after the disruption. If 
that does not lead to anything, you could use the packet marking feature 
to follow single packets through the dom0 kernel and find out where they 
get stuck (if they do).
But all that is nothing I am very familiar with (like in "I do that 
daily"), so I guess the developpers could be of much more help.
