I'm still seeing this issue in Ubuntu 14.04 on Ec2, despite using the
latest kernel release:
3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 x86_64
x86_64 x86_64 GNU/Linux
Here are some of the logs I found:

Seth: I've been testing the proposed kernel fix for the past few days,

log lines in the kernel.log:

Seems that the `xen_netfront: xennet: skb rides the rocket: 19 slots` is
a different issue thats already been reported:

No kernel panics at all from the nginx haproxy server this week. The
kernel patch you provided has made the issue go away. Do need any logs
or something from the server? Thanks for the kernel fix, I really
appreciate it !

I have applied the kernel fix that you provided to the server and its
been running for about a week now without any issues. I'll let it run
for a week more to see if the issue pops up again.
