Title:
  Networking and ACPI conflicts

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The Linux kernal seems to have an issue with my on-board networking
  adapter and the ACPI of my computer.  The boot log provides this bit
  of information:

  [   12.236250] ACPI: resource nForce2_smbus [io  0x0700-0x073f]
  conflicts with ACPI region SM00 [io 0x700-0x73f]

  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 the previous 12.04 kernel, 3.2.0-23.36, there were two
  workarounds.

  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.

  or

  2)  Add "forcedeth msi=0 msix=0" to /etc/modules

  If you booted normally without following either of the above steps and
  then tried to modprobe, it wouldn't work.  If you tried to rmmod the
  module, the system would instantly freeze.

  With the new kernel update, 3.2.0-24.38, the above method number 1
  still works, but number 2 no longer works as a workaround.  It simply
  doesn't do anything.

  The replacement work around for the new kernel is you must add the
  line "exec rmmod forcedeth" directly underneath the beginning of the
  script section in the file /etc/init/module-init-tools.conf, then you
  must add "modprobe forcedeth msi=0 msix=0" to /etc/rc.local.  This new
  method doesn't work with the old kernel, and the old method doesn't
  work with the new kernel.

  I fear unless this long-standing bug is fixed once and for all so such
  hoops don't have to be jumped through, at one point the kernel may
  receive some update to where no method will be able to get this to
  work at all.

  For the record, none of the various GRUB tweaks, such as acpi=off or
  acpi=force, did anything.
