Hi Harald, Since some drivers do the soft kicking. That is if BIOS has enabled watchdog, then kernel driver kicks the hardware till user space watchdog daemon comes along. This can help sove the problem in kdump which kdump kernel reboot before vmcore saving is finished. That problem is triggered because watchdog started in 1st kernel and timeout because of stopping being kicked. I noticed in 04watchdog the watchdog.sh will start watchdog if /dev/watchdog exists. I am just wondering if it's needed to start watchdog by accessing /dev/watchdog. If starting watchdog is not needed, I want to make some code change of watchdog.sh. What's your suggestion?
