Jo, Kzysztof, 3.16/3.17 currently suffer from a change affecting the
kernel/module split. I am trying to get behind this. But right now now
PV guest works without re-compiling the kernel with
CONFIG_RANDOMIZE_BASE_MAX_OFFSET=0x20000000 (resulting in the same
layout as before).

The stack trace itself does not directly contain Xen specific functions
(actually that is not a surprise since this is transferring to dom0,
which uses the real NIC). So we are talking about an issue related to
receiving large transfers on a NetXtreme BCM5704 (that would be the tg3
driver). Comment #4 is a bit confusing. I assume it meant a 3.17 kernel
works on bare metal but not as dom0 which would be the max offset
problem. The other question would be: does the file transfer work, when
not booted as dom0?

Maybe as a first step for further debugging I would try to upgrade the
dom0 to the most current Trusty kernel (3.13.0-34.60) or maybe the
proposed version manually from [1]. That would be 3.13.0-35.62 (you
would need linux-headers (arch and all) linux-image (arch), and linux-
image-extra (arch). For checking 3.17, we need a special kernel.

Title:
  [xen] The kernel panics on transfer

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I got a 1GB network card and I tried to copy my xen image (30GB), so I run
    nc -l 3000 > image.dd
  on xen dom0
  and tried to send using nc from another remote machine. 

  The machine crashed after 3-15 seconds. I tried this many many times.
  I managed to get bug using netconsole (attached).
