Title:
  [ASRock N68-VS3 FX] Networking and ACPI conflicts

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The Linux kernel seems to have an issue with my on-board networking
  adapter and the ACPI of my computer.

  On doing some research this seems to be a very old and somewhat common
  bug that no one has ever done anything about.

  This bug results in two things:

  My on-board networking doesn't work, and trying to restart or shutdown
  the computer freezes the system.

  With an older 12.04 kernel, 3.2.0-23.36, there were two workarounds.

  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1003297

  And in  a more recent version there was still a practical workaround

  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1003297

  The first mentioned of these still works:

  1) Boot into rescue mode, drop to the terminal, run "rmmod forcedeth"
  then "modprobe forcedeth msi=0 msix=0" then resume a normal boot. This
  enabled both networking and regular ACPI functions.

  But is a one-off that needs to be repeated at every start up and
  several graphics drivers do ot function well until the next normal
  boot.

  So that is very much a compromise.

  The more stable work arounds listed at the references cannot now be
  applied because the structure of the kernel has changed.

  I assume that a work around could be produced but my knowledge is
  insufficient to do it myself.

  I would dearly and urgently love to find a solution as I have an
  unusable PC at the moment.

  DONt Let Me Go Back To Windows!
