Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

Found this explanation and solution on the Internet:

...
lm-sensors appears to have stopped working in Ubuntu Karmic Koala (basically for any distro running Kernel 2.6.31). If you look at your Kernel messages, you will see something like this:

ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__
[0x295-0x296]
ACPI: Device needs an ACPI driver

If you want to restore the old behaviour (which might be dangerous) add: "acpi_enforce_resources=lax" to the kernel cmdline when booting (or add it in grub.conf to make this permanent).

To add acpi_enforce_resources=lax to your Grub, in Ubuntu Karmic,

1.press Alt + F2, and enter: gksu gedit /etc/default/grub
2. And enter the following line: GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
3. Then save the file.
4. Run this in console: sudo update-grub2

This is copy/pasted from the following link(it is missing step 4):

I have the same problem !!!
lm sensor doesn't work !
I tried with grub with: GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
But with sudo update-grub2 i had this:

/etc/default/grub: 9: acpi_enforce_resources=lax: not found

[Petar Velkovski (pvelkovski)]

francesco this is my output of /etc/default/grub:
-------------------------------------------------------------------------------------------------------------------------------
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"

# Uncomment to disable graphical terminal (grub-pc only)

# Uncomment to disable generation of recovery mode menu entrys
#GRUB_DISABLE_LINUX_RECOVERY="true"
--------------------------------------------------------------------------------------------------------------------

Are you sure that you have typed it correctly?
Try it again, AND DO NOT COPY PASTE THE WHOLE LISTING!!! I made other changes to it, so that it would suit my needs better!

[Petar Velkovski (pvelkovski)]

@francesco bat
and report back what you did no matter if you succeeded or not.

[francesco bat (nerobat2004)]

Hello !
Today i solved in this way:

sudo gedit /etc/default/grub

and i modified the old string:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

in

GRUB_CMDLINE_LINUX_DEFAULT="acpi_enforce_resources=lax quiet splash"

Now it's all right !
But i hope that is being to solve in official way, beacuse many people couldn't solve it ! :-(

[Petar Velkovski (pvelkovski)]

By the way I forgot to mention that this is not officially a bug. I remember reading in some of the linux kernel 2.6.31 release notes that lm-sensors has been disabled by default because it made problem with some other code. But it's good that we have this workaround. It works for me (and obviously for others too) but probably it can affect some systems in a bad manner.

[francesco bat (nerobat2004)]

What problems ?
I would know these problems, because if it can do me problem I edited the grub as it was before. ;-)
Bye

Hypothetically, what's the right way to get temperature data if the module isn't supposed to be used anymore? Is it safe to use LAX here?

[Ricardo Jorge Borges Guimarães (rjbgbo)]

https://bugs.launchpad.net/ubuntu/+source/lm-sensors/+bug/478762/comments/3

Thank you.
This ok.

[Jeremy Nickurak (nickurak)]

That's a work-around... but the warning would seem to suggest that this isn't safe. Is there an API/ABI/socket/sysfile that we're supposed to used? Until that's the case, this is a regression. Given that, and that people might be using this to tell if a system is running at a safe temperature, this should probably be a higher priority than Low.

[Jeremy Nickurak (nickurak)]

Hrm, nevermind, after adding the lax option, sensors-detect found a module to load. Odd.

[Paul van Genderen (paulvg)]

Is this bug reproduceable with the current 9.10 (2.6.31-20-generic) or current lucid (2.6.32-21-generic) kernel?

[Petar Velkovski (pvelkovski)]

Without the "acpi_enforce_resources=lax" boot option the Fan sensors are not reachable in Lucid! But again keep in mind that there was a warning for using this option that it may lead to system instability (not in my case).

I have no working sensors apart from 1 hdd temperature (used to work with 9.04)
