No problems with the patch here, but a general observation about
hibernation.

When I hibernate here, the monitor goes off immediately, whereas
peripherals, such as keyboard go off approx. 5-10 seconds later, presumably
after RAM has been fully saved to disk. If you turn off at the wall prior to
that, then I'd suspect you'd have problems resuming.

So perhaps waiting 5-10 seconds before turning off at the wall may make the
difference.

Also make sure that you're distinguishing between 'sleep' mode, and
'hibernation' - they're not the same. You can turn the power off with
hibernation, but not (safely) with sleep / standby .
