Hello,
I have a question about watchdog. I want to use watchdog reset to trigger “Fail-over Rootfs Slot Switching”.
In dmesg:

# dmesg | grep watchdog
[    9.213983] systemd[1]: Using hardware watchdog 'NVIDIA Tegra186 WDT', version 0, device /dev/watchdog
[    9.214002] systemd[1]: Set hardware watchdog to 2min.

But I don’t know which process is kicking dog in 2 min to avoid watchdog reset.
Could you give me the way to stop kicking watchdog? Thank you!
