I've started to be suspicious about the hardware issue. Not sure if the
sensors are not functioning properly or readings are erroneous.

Also affects my brand new Thinkpad X1 Extreme Gen 2.
The errors pop up when the CPU is stone cold (i.e. upon waking after an
overnight sleep in temps <10C)

1) Yup, system not hangs up, but I feel the system response slower when it
happens. E.g. keyboard mouse not work for seconds. I can check if the
cpufreq be changed next time I get machine.
2) Not saw the over temperature by command sensors. Isn't it reported from
sysfs? If not, I can check it

It reads from hwmon instead of thermal zones, which should be used on
modern Intel platforms.

Alex,
1) This warning should be harmless. Does it affect actual usage?
2) What's the temperature reports under thermal_zones sysfs?

This bug has been reported a few times in Ask Ubuntu. Just today (July
3rd, 2019) I was going back through `dmesg` and by chance I noticed on
June 22nd, 2019 the errors appear about a dozen times.
I've been on the same kernel version 4.14.114 LTS for a couple/few
months now but I did flirt with
Same problem here with an HP Omen Laptop.
Whenever I run the "sensors" command under high load, all CPU cores are
below 90°C. I never saw the critical value of 100°C.

As I remember, I didn't have that problem in Ubuntu 16.04 but don't
remember which kernel it was. I was updating the OS whenever there are
new updates, so most probably I've used numbers of different kernel
versions. This device is my daily laptop and it's not possible to
install and test Ubuntu
So it's a regression? Do you remember the kernel version that doesn't
have this issue?

I tried with 4.17 and 4.18-rcx kernels and problem still persist. Also
suspend mode is not working correctly and consuming huge battery in
suspend mode. If I put the device into suspend mode without setting CPU
governor to "powersave", CPU burns like hell when suspended.

v4.18 kernel[0].
If this bug is fixed in the mainline kernel, please add the following

it be a broken package problem?
