Yeah, this did the trick on AMD/Barcelona!
NMI: 11310 14932 11729 12705 11207
13454 13378 10714 14526 11986 10973
10765 12669 12093 13430 9661 Non-maskable
interrupts
KernelTop works just fine:
------------------------------------------------------------------------------
KernelTop: 1019 irqs/sec kernel:27.9% [NMI, 1000000 CPU
cycles], (all, 16 CPUs)
------------------------------------------------------------------------------
