Can you do me a quick favor and 'cat /proc/interrupts |grep NMI' before
each of your suspends.  I want to double check a piece of code.  Your
bugzilla postings showed your system starting with no nmi watchdog running
but after the resume the watchdog started running on cpu1.  I am hoping I
fixed that issue too.

Thanks.
