Public bug reported:
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.
