Thank you very much for you response, I tried this right now, but 
unfortunately I still get:

"2025-09-20T11:49:06.100523+02:00 ceph-1 systemd-modules-load[880]: 
module 'wdat_wdt' is deny-listed (by kmod)"

when booting the system and the module is not loaded.

So my workaround remains adding

@reboot modprobe wdat_wdt

to crontab, which is certainly very amateurish, but at least the module 
is loaded and watchdog works.


Kind regards
Thomas
