I'm not sure if this is related but just in case. I upgraded from 16.04.1 LTS to 18.04.2 - straight after I started getting alarms from my SNMP monitoring, low voltage VBat etc. Upon checking the sensors output I can see it's all messed up:

May be a red-herring - just thought I should bring it up. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768976/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
