Hi everyone,
I enabled the iTCO watchdog in my Linux system.
sudo cat /dev/watchdog perfectly reboots my system. But, is there a
way to find out on each boot if the machine was rebooted due to a
watchdog timeout or not?
Any ideas?
Thanks,
Naveen

If the hardware supports it, the driver could set the reboot reason
in its probe function.

I didn't say that one exists, nor that it is possible to actually implement
what I suggested. I only stated a possibility. Please feel free to implement,
test, and submit such a patch yourself.
Thanks,
