silent shutdown, "watchdog did not stop"

Hi,

The wiki has recently changed from suggesting to disable watchdogs for workstations, to making sure they were enabled.

I had watchdogs disabled (nowatchog in cmdline and blacklisted iTCO_wdt) because of the wiki suggestions, and because they helped with silent shutdowns, as the kernel msg below is a level 3 error and brings down the splash screen to print the error before shutdown.

Feb 25 11:31:35 aquarius systemd[1]: systemd-reboot.service: Deactivated successfully.
Feb 25 11:31:35 aquarius systemd[1]: Finished System Reboot.

Is there a way to keep the watchdog without breaking silent shutdown?

Thanks!
