For HP watchdog, it's mandatory
https://www.kernel.org/doc/Documentation/watchdog/hpwdt.txt

lyt_yudi has also reported crash with nmi_watchdog on his dell server when ipmi_watchdog is loaded.


And I have also seen a lof of bug report on the net with nmi_watchdog.


>From my point of view, nmi_watchdog is only usefull with softdog, so if you have hardware watchdog,
disable it can avoid problems.

But I do not really understand the why someone should disable the nmi_watchdog?
