It seems the root of problem in dom0 messages above. Is it HW failure or
some internal kernel structures overflow?
 From the stack, it reminds me this issue is very likely same with
the one which has been fixed. There is something wrong with counting
slots in netback, and then responses overlapps request in the ring,
and grantcopy gets wrong grant reference and throws out error in
grant_table.c. See
http://lists.xen.org/archives/html/xen-devel/2013-09/msg01143.html
There were some back and forth work for this issue, but seems the
fix patch exists since v3.12-rc4. Would you like to have a try with
newer kernel version?

FWIW the patch you mentioned was backported to the kernel he used.

Yes, it exists in 3.10.25 he used.
Based on assumption of counting slots in netback causing this issue, maybe http://www.spinics.net/lists/netdev/msg260017.html is the right fix. This patch fixed an issue caused by counting slots, and it went into net-next tree, git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git

Thanks
