I'm using w83627hf_wdt and when I kill (-9) watchdog processus the kernel says:

Of course, the system never restarts, which is quite annoying for a watchdog
service ;-)
I'm pretty much sure that this is a kernel problem. Some reports on the web
seem to suggest the same. After all the watchdog code didn't change in this
regard.
Anyway, do you have NOWAYOUT set?
Also it would be nice if you could test with the software watchdog driver
softdog just to see whether this is a driver issue.

Hi, I just give a try with nowayout and it still have the same behavior.

So I tried with softdog driver and I got the same message:
Apr 29 16:00:43 dedibox kernel: [17711.068562] SoftDog: Unexpected
close, not stopping watchdog!
Then the server performed an hard reboot. Weird.
