watchdog and crash dump really conflicts to some degree, from the watchdog
point of view it can reboot system whhen kdump kernel hangs. But from kdump
point of view it want ensure saving the vmcore for later debugging.
Maybe we can only select only one in this case.

I thought this problem was resolved (atleast conceptually) last time
when Don Zickus brought it up.
He mentioned that it was concluded that keep watchdog interval long
enough, say 60 seconds and keep on kicking it fast

Hi Dave,
In kdump kernel watchdog could interrupt vmcore capturing because we
have no way to disable/stop it while crashing happens.
Add a module parameter stop_before_register so watchdog can be stopped
before register in driver loading path. Thus we can try to load the
watchdog driver as
