Hi!

Let's take a look at hibernate() callers:

drivers/mfd/tps65010.c: calls hibernate() from IRQ contex, based on HW
                        event

No it does not. Look again.

kernel/power/autosleep.c: calls hibernate() when it thinks it might be
 			  a good time to go to sleep

Ok, you are right, it is there. But I don't believe anyone uses this
configuration.

Best regards,
								Pavel
