I had already explained that everything was solved by your resolution of where the error messages came from. I was convinced that it had something to do with the ASN script, but it was your script. Both at the same time does not work.
I had already mentioned in the other thread that restarting the firewall rules causes the Tor chains to be deleted, but no one else responded.
I only found out now that the ASN script executes a restart.
As suggested, I carried out a bios update, but this did not bring any improvement.
My search then brought up the tip
“After uninstalling cpufrequtil and restarting IPFire, amd_pstate_ut errors disappear.
After reinstalling cpufrequtils and restarting IPFire, the errors are visible.”
from here
This solves everything except the question of why the Tor entries in the iptables are deleted when the firewall is restarted.
