Solved this with a patch from fedora:
https://src.fedoraproject.org/rpms/irqbalance/blob/main/f/0001-Drop-ProtectKernelTunables.patch

Maybe the patch
https://src.fedoraproject.org/rpms/irqbalance/blob/main/f/0001-irqbalance-ui-check-if-using-a-negative-index-of-buf.patch
is also interesting.

If desired, I can create a SR.
