Hi,

I recently got hold of new hardware and want to run pve-2.6.18. I have noticed in the "/proc/interrupts" that I get a lot of NMI interrupts (below is just after a reboot):
Code:
           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5       CPU6       CPU7       CPU8       CPU9       CPU10      CPU11

I have tried kernel 2.6.24 and 2.6.32. They both show 0 NMI. I am able to remove it the NMIs on 2.6.18 by booting the kernel with "nmi_watchdog=0", but that does not seem like the correct solution.
I have two identical boxes - Intel S5520UR mainboard, Westmere XEONs, Adaptec 5445z and at the moment both a Myricom 10GbE and a DXH510 for testing.
Anybody else who sees these NMIs on 2.6.18? Is it something to be concerned about?

Thanks in advance,
Bo
