thermald[583]: sysfs read failed /sys/class/thermal/thermal_zone3/temp

[francoism90]

It's filling up the journal, any debug info needed why this is happening? :)

System:
HP 360x
Intel i5-7200U
Arch Linux 4.15.9

Thanks!

We need to see why read is failing: what is output of #cat /sys/class/thermal/thermal_zone3/* Thanks, Srinivas

This is a wifi kernel driver issue, where all reads are giving invalid data. Only thing can be really done is to remove error message. Thanks, Srinivas

I accidentally copied information from my workstation, sorry!

This is the correct output/debug:

# cat /sys/class/thermal/thermal_zone3/*

This also needs kernel driver fix. Currently there is no way to avoid sysfs entries even if certain features are not present. Thanks, Srinivas
