Seems like it is not that simple here;

suspend_enter():

	if (!error) {
		if (!suspend_test(TEST_CORE))
			error = suspend_ops->enter(state);
		sysdev_resume();
	}

[it reaches this point]
	arch_suspend_enable_irqs();
[but not this one]
	BUG_ON(irqs_disabled());

 Enable_cpus:
	enable_nonboot_cpus();

Do I have screaming irq or something?
