thermal thermal_zone4: failed to read out thermal zone (-61)

[Juno Computers]

Thermald can't read zone4. It's making my fan go crazy, this issue seems to be a bit more controlled in 18.10.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1803881

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.20 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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This issue happens with the stock 4.15 kernel. I have upgraded the kernel to 4.18 and 4.19 and was getting the same issue. I managed to get rid off the error now. It seems it does not like intel_pstate. I added intel_pstate=disable to grub and the error has gone away.

[Juno Computers (junocomp)]

I also want to add that my pc is the newest Intel NUC8i5BEH. I will try the latest kernel and will report back.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

These are kernel bugs, so better to file in kernel bugzilla.

cat /sys/class/thermal/thermal_zone4/type

[Colin Ian King (colin-king)]

The issue is in the iwlwifi wireless driver, specifically the error -61 (ENODATA) is being reported by the call to iwl_mvm_tzone_get_temp() in in drivers/net/wireless/intel/iwlwif/mvm/tt.c

Looking at this failure case it could be because there is a mismatch between the expected firmware blob and the actual installed (nor not installed) firmware blob for this driver.

Can you try installing or re-installing the linux-firmware package to see if this helps. You may need to re-boot the machine for this to be activated.

I suggest using:

sudo apt-get install --reinstall linux-firmware

Let us know if this allows one to read cat /sys/class/thermal/thermal_zone4/type
iwlwifi_1

[Juno Computers (junocomp)]

Hi, I no longer have the laptop in which I used to report the issue. On the other hand the issue shows up on 2 other laptops that I have, the main difference is the thermal number.

I have test cat /sys/class/thermal/thermal_zone(number error)/type and it does say iwlwifi_1.
