Watchdog running anyway

Hi!

I tried to disable watchdogs in my GRUB kernel parameters to reduce power usage, but I don't think this has done anything, as I still get messages like this on shutdown:

watchdog0 did not stop!

Even after adding the below kernel parameter:

nowatchdog

Re: Watchdog running anyway

Hello.

These messages are completely benign. You may ignore them.

Some watchdog modules seem to not support `nowatchdog`. You might blacklist the module completely to turn off the function. But the only thing you get that way, aside of not seeing the harmless message, is the need to use your hand to press the reset button. And do that blindly, because you may not be able to tell whether it’s a proper lockup or the system is just temporarily overloaded.
