I think it has 11 thermal zones judging by
/sys/class/thermal/thermal_zone* going from 0 to 10.

And the kernel default seems to be

   CONFIG_THERMAL_DEFAULT_GOV_STEP_WISE=y

but presumably this is F34 then setting it to 'userspace' (the kernel
config comes from the F34 one too, although it's been tweaked for the
machine).

I suspect I could just turn off THERMAL_GOV_USER_SPACE and get rid of
the message, that's not the issue.

The issue is "why is the kernel spewing pointlessly the same message
over and over again?"
