As I can't reply properly to an old thread I'm creationg a new one. Sorry about that please refer to:

I had a very similar issue on Debian.
Upgrading the guest with recent kernels and userland tools didn't helped unfortunately.
The solution I found was to disable the TCP checksumming on the virtual interface (using ethtool).

You can have it done automatically using a slightly custom vif-scritp:

dir=$(dirname "$0")

. $dir/xen-script-common.sh

evalVariables "$@"

: ${type_if:=vif}
[ "$type_if" = "vif" ] && ethtool -K $vif tx off
  ethtool -k $vif >> /tmp/debug

$dir/vif-bridge "$@"

Works here.
