I've done some googling about "xennet: skb rides the rocket" and it seems to be related to some internal Xen networking stuff, maybe too many packets than the kernel can handle? (In particular this thread:

I have seen it, and I would assume a lot of other have seen it as well. It happens with the Linode provided kernels as well if you have a lot of traffic so I don't think your custom kernel is at fault.
It doesn't appear to cause any disasters, though, so I haven't really much investigation.
