Actually, on one of the boxes it doesn't seem to be working at all:
activating NMI Watchdog ... done.
testing NMI watchdog ... CPU#0: NMI appears to be stuck!
This is on a Tyan Dual AMD MPX board with two MP 2000+ CPUs.
/proc/interrupts shows:
CPU0 CPU1
0: 4897433 4904751 IO-APIC-edge timer
1: 1 1 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 1 0 IO-APIC-edge rtc
16: 699524 700761 IO-APIC-level dpti0
19: 12480119 12480207 IO-APIC-level eth0
NMI: 0 0
LOC: 9801455 9801319
ERR: 0
MIS: 13
I'll try reenabling it on the other (Intel) boxes where I think it
actually does work, and see if anything results.

I'll do the serial console dance next time and get some sysrq-T output.
