I tried disabling nmi_watchdog by adding it to kernel boot params..like this;
title Red Hat Enterprise Linux WS (2.6.9-89.0.19.ELlargesmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-89.0.19.ELlargesmp ro nmi_watchdog=0 root=LABEL=/1

But NMI is still showing interupts, I thought these shud show 0 now
$ cat /proc/interrupts
