Yeah, you could try my sure-fire way to trigger it:
* boot the box without any "nmi_watchdog" tweaks on the kernel cmdline -
i.e. it should be enabled.
* turn off NMI watchdog through powertop or directly through
/proc/sys/kernel/nmi_watchdog
* suspend to disk
Now when you resume, you should either see unknown reason 2c or 3c.
