[Asus A8JP] Fan speed control is frozen

[Jörg-Karl Bösner]

Behaviour:

The fan speed remains on the same level after the kernel was booted. That means that the fan is still off when the Laptop is booted with cold hardware, the fan remains off, leading to an emergency shut down at100°C.

If the system is booted when still hot, the fan is turned on at maximum speed. The fan stays at this speed, even when the system has cooled down.

This problem did not happen before upgrading from 13.10 to 14.04.

When I boot an old installed kernel (3.5.0-44-generic), the problem does not occur.

Expected Behaviour:
Fanspeed is selected to actual temperature of the system

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hello Joseph!

I will try it, but it may take a few days, since I'm not at home till
monday...

Best regards,

Fan speed is also frozen on HP 6830s an xubuntu 14.04. I downgraded to 13.10 and everything was working again.

[penalvch (penalvch)]

pschroth, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:
ubuntu-bug linux

Hello Joseph!

I did try it with the new upstream kernel, it did NOT solve the problem. The problem also occurs on all kernels when suspending to RAM and starting it again. The fan behaviour is the same as when the machine is booting regularly: The speed is frozen to the actual hardware temperature and never adjusted.

Best regards,

Jörg

[penalvch (penalvch)]

Jörg-Karl Bösner, the next step is to fully commit bisect from Saucy to Trusty, in order to identify the offending commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[H Jalonen (h-jalonen)]

I experienced similar problems with my laptop HP Compaq nc6120 in Ubuntu 14.04. The bug is also present in Debian testing when using kernel 3.13 but not with kernel 3.11. Therefore this seems to be a wider laptop issue and not only Asus-specific and also probably caused by bug in the upstream kernel.

I'm guessing the reason is this upstream regression bug https://bugzilla.kernel.org/show_bug.cgi?id=71711

Hello fellas,

I have a similar problem after fresh new instal of 14.04 Lubuntu on HP nc6120. Chose Lubuntu as it is lighter than Ubuntu for this machine. The fan behaves as described by Jörg. Similarly psensor does not show fan at all, while the temperatures it shows are frozen at boot level hence graphics are straight lines. The machine is with the latest updates.

Would you like me to extract some more info? Should I follow https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue or else?

Cheers,
Bernard

OK, bisect will be finished next week (at least, I hope it so). ATM it is narrowed down to the follwing commits:

[Jörg-Karl Bösner (joerg-y)]

OK, almost finished, three commits are left:

469f643 ideapad_laptop: introduce struct acpi_device pointer to ideapad_private structure
11fa8da ideapad_laptop: introduce #ifdef CONFIG_PM_SLEEP for PM specific code
cc8ef52 ACPI / AC: convert ACPI ac driver to platform bus

Since the last one was mentioned earlier in exactly the same matter (https://lkml.org/lkml/2014/4/10/649), I would suggest that it's a good point to start at...

[penalvch (penalvch)]

Jörg-Karl Bösner, one would actually want to test the commits mentioned to verify this finding.

[Joonas Saarinen (jza)]

Christopher: Can the fix (Revert ACPI / AC: convert ACPI ac driver to platform bus) be backported to the trusty 3.13 kernel? Looking at the upstream bug (https://bugzilla.kernel.org/show_bug.cgi?id=71711), it affects quite many laptops and their fan control is now also broken with the stock Ubuntu 14.04 install, leading to cautiously high temperatures.

[Oliver Joos (oliver-joos)]

For me it is solved with kernel 3.13.0-32 from https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa

Careful users should wait a few days to get the fixed kernel as a normal update!

[Joonas Saarinen (jza)]

I have verified that 3.13.0-32 also works for HP 2230s which suffered from the same problem.

[Jörg-Karl Bösner (joerg-y)]

3.13.0-33-generic works for me, so I think we can consider it as fixed?
