# which I answered the following way (I hope it'll be complete on here):

Hi again,
unfortunately you didn't specify how deeply I should dig into /sys/class/thermal. So you get the lines from # BOF # to # EOF # below. I hope they're readable without more comments.

The most remarkable changes, in my eyes, had happened within "thermal_zone1".

Best regards,
Manuel Krause

# BOF #
Following ones are all from /sys/class/thermal/ which are links to -> ../../devices/virtual/thermal/

I've listed the directories in sections of cooling_devices and thermal_zones separately for each bad/good kernel. For Emailing purposes only. You can merge them into a spreadsheet for your evaluation on your own. I've left out reporting some subdirs and subdir's values that _really_ didn't seem to need attention.

Also, I've had collected the #sensors output for each readout, having reproduced nearly the same workload, represented by the "Fan speed" (thermal_zone4==FDTZ).

And I've done my very best to not produce typos or c&p errors.
