Title:
  nVidia on board network card with forcedeth driver freezes systems on
  AM3+ CPU

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have a Ubuntu 13.10 amd64 system with a nVidia Force3 mainboard with
  nVidia forcedeth-driver network card running on a Phenom X4 965
  processor.

  The network is completely 1000mbps wired and the main server is a HP
  Proliant microserver running Ubuntu 13.10 amd64.

  When the network transfer at 1000mbps, the system becomes
  unresponsive, and usually freezes for a long time; even sound and
  mouse freeze.

  When the data trasmissione is ended, the system starts running
  smoothly again.

  Googling around I found that there was a workaround for similar
  network problems regarding AM3+ CPUs on nForce mainboards, and the
  problem seemed related to a a problem between forcedeth and ACPI.

  The workarounds that suggest removing forcedeth module at start-up and
  reloading with "modprobe forcedeth msi=0 msix=0" seem to work on my
  system and I have not had freezes again.

  I attach debug info requested by penalvch.
