[Voyage-linux] Re: Broken watchdog?

[Robert Rawlins]

Hi Thomas,

Thanks for your advice on this. I will give this a try later today and see if it solves the issue. I did check that -no-action wasn’t listed in the watchdog options, I also made sure that it wasn’t defined in the daemon start script for watchdog.

I'll keep you posted on this.

Robert

i've stumbled upon the same "problem". I "fixed" this with loading the 
geodewdt module with "nowayout=1" option (place "option geodewdt 
nowayout=1"  in /etc/modprobe.d/options) . 

never used watchdog before the ALIX boards, but maybe it needs the 
"repair-binary" option set to a real binary. it seems that the default 
is /usr/sbin/repair which doesn't exist.

also check that /etc/default/watchdog doesn't contain "--no-action"

PS: replace geodewdt with your watchdog kernel module name
