There is a bug report filed against thermald:

Erratic behavior of CPU frequency control under load

People get the same errors you report:

Comment #18 says to:

try running thermald in a window from command line.

systemctl stop thermald  
#thermald --no-daemon --loglevel=info  

Then do what triggers this, and attach the output of the above
command.

On my machine I can’t duplicate the problem with thermald and tlp loaded. I opened five terminals and typed into each one:

while true ; do : ; done

All that happened is five cores are running at 100% and 3100 MHz. No throttling has occurred but it did make the two laptop fans run on low speed. Normally in Linux they are off (or at least I can’t hear them). System temperature is 88 Celsius and keyboard is still responsive to type this answer. The living room does feel a bit warmer though…
