One of our machines here a Thinkpad T480s on openSUSE 15.2 kernel
5.3.18-lp152.33-default. In general this machine was upgraded from LEAP 15.1 to
15.2 and then the problems started to show. The CPU is constantly hotter while
working. by 20�C.

This machine now freezes sometimes completely.

The machine is then
- not pingable
- no keyboard interaction works
- lid close/open does nothng
- no mouse interaction works
- the notebook is really warm
- When a freeze happens also a trim of the journal happens... e.g. we loose the
whole journal for the day.
- We SSH'ed into the machine and watched via "htop", "journal -f" and
"sensors". WHen the machine freezes, there is no significant load via htop
seeable, there are no interesting logs in journal and sensors shows that it is
simply hotter.

Interestingly, we upgraded another machine before (also a Thinkpad T480s) and
this does not have any problems.

We are btw on the latest firmwares using fwupdmgr.

What should we try? How can we debug it?
