- nmi_watchdog=NUMBER[,panic]
- NUMBER can be:
- 0 don't use an NMI watchdog
- 1 use the IO-APIC timer for the NMI watchdog
- 2 use the local APIC for the NMI watchdog using a performance counter. Note
- This will use one performance counter and the local APIC's performance

- When panic is specified panic when an NMI watchdog timeout occurs.
- This is useful when you use a panic=... timeout and need the box
