Subject: acpi/iwlwifi: thermal thermal_zone3: failed to read out thermal zone (-61)

Hi,

I am seeing this with Linux v4.18.y and v4.19-rc4.

Investigating thermal_zone3...

# cat /sys/devices/virtual/thermal/thermal_zone3/type
iwlwifi

I have the following iwlwifi device and firmware installed...

[ 10.476589] iwlwifi 0000:04:00.0: loaded firmware version
36.e91976c0.0 op_mode iwlmvm
[ 10.519441] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band
Wireless AC 8265, REV=0x230

What informations do you need and how can I help?

Thanks.

Regards,

This is normal, though annoying, and was discussed before. The thermal
framework is trying to read the temperature as soon as the zone is
registered and this causes that warning. Our device only provides the
temperature when the device goes up, so reading before that will always
fail.
