https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188369 --- Comment #12 from miguelmcl...@gmail.com --- 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. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"

Dunno if this will help in anyway... I lack C skills and I certainly don't know
much about the Xen code...
In anycase I will post my findings:
I decided to compare the changes on 9 and 10, because 9 is working for me.
I noticed that warning comes from netfront.c:
if (txr->status != NETIF_RSP_OKAY) {
printf("%s: WARNING: response is %d!\n",
__func__, txr->status);
}
So I decided to try and find out whats "NETIF_RSP_OKAY", which apears to "come
from" sys/xen/interface/io/netif.h
This is the diff from 9 to 10 (stable) src, could any of this changes be the
cause!?
