[Bug 1011864] Re: Winbond super I/0 chip W83627DHG and nForce2_smbus conflicts with ACPI
Morten Hansen, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number>
Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
** Tags added: needs-upstream-testing
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete

Title:
Winbond super I/0 chip W83627DHG and nForce2_smbus conflicts with ACPI
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
* What I expected
To be able to use fancontrol to manage CPU fan speed
* What actually happens
ACPI and the module for the W83627DHG (W83627ehf) conflicts. the moudle w83627ehf is therefore not loaded correctly and temperature and fan RPMs can therefore not be read.
* How to recreate the problem
Happens every time I turn on the computer
I have tried booting with acpi_enforce_resources=lax, but that results
in system freezes.
Booting with acpi=off allows w83627ehf to be loaded, fancontrol to
control the RPMs of the CPU fan, but also creates problems with sound
playback in music and video files and low frame rates when playing
videos (probably related to the sound issues)
I've also tried booting with the options suggested here:
https://wiki.ubuntu.com/DebuggingACPI. All options other than acpi=off
and acpi=ht leads to either a non-responsive system during boot or a
system that freezes. The freezes don't always start right after the
system has booted. Sometimes it takes hours (maybe something to do
with suspend?) but eventually the system will lock up
In dmesg I have found the following conflicts between ACPI and the I/O
chip
[ 10.856429] ACPI: resource nForce2_smbus [io 0x1c80-0x1cbf]
conflicts with ACPI region SM01 [io 0x1c80-0x1cbf]
[ 10.856431] ACPI: If an ACPI driver is available for this device,
you should use it instead of the native driver
[ 10.946400] [Firmware Bug]: ACPI(IGPU) defines _DOD but not _DOS
[ 10.948958] ACPI: Video Device [IGPU] (multi-head: yes rom: no

[ 10.972197] ACPI: resource w83627ehf [io 0x0295-0x0296] conflicts
with ACPI region SEN1 [io 0x295-0x296]
[ 10.972200] ACPI: If an ACPI driver is available for this device,
you should use it instead of the native driver
I haven't been able to find ACPI drivers for either the nForce2_smbus
or w83627ehf
