See: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188369 I've reported it months before on the xen-devel list too, but IIRC that's where the most recent info is... Sadly all I could do was test and report my findings, but it seems something changed regarding tso or checksum in the netfront code or even elsewhere, I honestly have no idea, but I found a very similar issue on windows guests running on netbsd hosts cause the PV drivers were assuming features the netbsd backend doesn't have. My theory is freebsd 10 as a similar issue, in my findings disabling tso/checksum stops the panic but I still had no network. Anyway if interested I guess all info is in the PR. I do hope this gets attention and maybe someone has the knowledge/time to fix it. On May 28, 2015 5:03:56 AM GMT+01:00, Dean Anderson wrote: >Yes.
