"core temperature above threshold, CPU clock throttled" causing Dell G7 laptop to freeze intermittently on 20.04

  • 772

I have a Dell G7 15 7590 laptop. I recently installed Ubuntu 20.04.

Now one to two times a day the computer freezes. Sometimes it comes back and sometimes I think a full restart is required.

cat /var/log/syslog shows:

Each time it freezes there are similar messages in /var/log/syslog

Perhaps it is is somehow related to the wifi?

I tried every suggestion in this CPU hardware errors in Ubuntu 17.04 and nothing worked.

I see other issues have been raised here on Launchpad and here on the Arch Linux forums

There are no issues with this laptop when running Windows and the laptop is brand new so I do not think it is a problem with the thermal paste or hardware issues.

I am almost always running the Chrome browser, but it does not seem tied to anything specific (i.e. CPU intensive tasks or GPU intensive tasks) and it has happened when I am not running Chrome as well.

Does anyone have any suggestions for me to try?

I have tried to run this with the nVidia 440 driver and the Nouveau driver and it happens in both circumstances.
