Hello,
On my Lenovo T580 I really often get a message in dmesg about the CPU
temperature being too high:

Looking at the temperature with lm-sensors, it seems perfectly in range:
iwlwifi-virtual-0
Adapter: Virtual device
temp1: +41.0°C
thinkpad-isa-0000
Adapter: ISA adapter
fan1: 0 RPM
acpitz-acpi-0
Adapter: ACPI interface
temp1: +43.0°C (crit = +98.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +46.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +44.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +46.0°C (high = +100.0°C, crit = +100.0°C)
Core 2: +44.0°C (high = +100.0°C, crit = +100.0°C)
Core 3: +44.0°C (high = +100.0°C, crit = +100.0°C)
pch_skylake-virtual-0
Adapter: Virtual device
temp1: +41.5°C
An idea what might be the problem?
This might be related to a general issue with ACPI on this model (see bug
#203199)
