While working Bugzilla #183 I figured out what was the problem... Net
grant tables...something that is marked as DANGEROUS in the kernel
config...is on by default. When net grant tables is compiled in bringing
up two interfaces in a domU crashes the domU kernel. But when I compile
both Dom0 & DomU without net grant tables I am able to use two
interfaces in domU with no problem. I don't know a lot about net grant
tables but could someone who know more about net grant tables take a
look at this?

                        
Jerone,

Did you not see Jim Dykman's updates and posts on this bug?
He's found the root cause, and is putting together a patch,
although some of it might be interim because it exposes
another resource shortage which will have to be addressed
somehow. Expect a patch from him in the next day or two,
and see the bugzilla entry (and previous posts on xen-devel)
from Jim for the details.

thanks,
Nivedita
