Hi, I'm having a bit of trouble using kern.watchdog.period. Every time I set it, my DELL 1850 turns off.
In two different SSH sessions, I did the following: cefeu:2642:$ sysctl kern.watchdog kern.watchdog.period=0 kern.watchdog.auto=1 cefeu:2644:$ sudo sysctl kern.watchdog.period=300 kern.watchdog.period: 0 -> 300 cefeu:2645:$ cefeu:2644:$ while : ; do echo "$(date +%H:%M:%S) $(sysctl kern.watchdog.period)"; sleep 1 ; done 18:50:48 kern.watchdog.period=0 18:50:49 kern.watchdog.period=0 18:50:50 kern.watchdog.period=0 18:50:51 kern.watchdog.period=300 This period is measured in seconds, isn't it ? dmesg follows: OpenBSD 4.0-current (GENERIC.MP) #946: Wed Sep 27
