+ This enables some cheesy code to save the last PM event point in the
+ RTC across reboots, so that you can debug a machine that just hangs
+ during suspend (or more commonly, during resume).
+
+ To use this debugging feature you should attempt to suspend the machine,
+ then reboot it, then run
+
+ dmesg -s 1000000 | grep 'hash matches'
+
+ CAUTION: this option will cause your machine's real-time clock to be
+ set to an invalid time after a resume.
