Hello Steve, yes, I have that device: # ll /dev/watchdog crw-rw---- 1 root root 10, 130 Sep 17 23:21 /dev/watchdog # ps uawwx|grep w[a]tchdog root 6 0.0 0.0 0 0 ? S Sep17 0:00 [watchdog/0] root 10 0.0 0.0 0 0 ? S Sep17 0:00 [watchdog/1] root 14 0.0 0.0 0 0 ? S Sep17 0:00 [watchdog/2] root 18 0.0 0.0 0 0 ? S Sep17 0:00 [watchdog/3] root 22 0.0 0.0 0 0 ?

S Sep17 0:00 [watchdog/7] root 12175 0.0 0.0 6236 2140 ? SLs 11:11 0:00 /usr/sbin/watchdog -v # grep -v ^# /etc/watchdog.conf ping = 144.76.XXX.XXX admin = root logtick = 360 realtime = yes priority = 1 So you think killing with -9 will indicate if I have hardware watchdog or just software?
