The one issue you mention ("Attempting to checksum a non-TCP/UDP packet,
dropping a protocol 1 packet") seems to be caused by an issue in netback.
See eg. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=583366 ; you
should be using at least 2.6.32.14 IIRC.

Actually I don't think so: Way too many people would stumble across such an
issue within the kernel. Chances this goes unnoticed for such a long time
are nil.

I am pretty sure the upgrade to the latest kernel will fix the issue for
you...
