UPDATE: I've been trying to bisect with git, so far I tried only to bisect the
changes here:

https://github.com/freebsd/freebsd/commits/stable/10/sys/xen/xen_intr.h

As they seem to affect netback/front and xn_intr


All three commit after and including the following are bad:
Improve the Xen para-virtualized device infrastructure of FreeBSD: …
gibbs authored on Oct 19, 2010
831bbfa  


The one before is the same version runnning on stable/9 it seems.


also disabling txcsum stops the panic when I try ssh-in but I stil see the
xn_txeof: WARNING: response is -1 message and it eventually times out.

One thing to note is that the panic is not related to the mbuf already on the
free list anymore:



Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
