Orange Pi Zero LTS: Hardware watchdog not rebooting in 22.02 but works in 21.08

[Fiesel]

The hardware watchdog /dev/watchdog does not reboot the board in a brand new installation with 22.02 image. What happens instead is the green LED on board goes off, both LEDs on ethernet port go on and thats it - boards halt.

However, if I flash previous 21.08 to sdcard everything works fine, even after I upgraded the installation via apt-get update & apt-get upgrade to latest packages.

I vaguely recall some other thread about 'watchdog breaking on newer kernel', did you search the forums?
