ACPI S1 and keyboard

[Pavel Machek]

Hi!

With latest ACPI and patrick's patches, S1 *somehow* works. I can
enter it, and can exit it, userland is still alive, but all hardware
devices are dead.

But patrick's code explicitely does not resume devices when returning
from S1:

        if (state > ACPI_SLEEP_S1)
                pm_send_all(PM_RESUME,(void*)0);

Does that mean my hardware is buggy, or is something wrong with
interrupts?

That's because none of the devices should be asleep in S1: it's "power-on"
suspend, which means about the only thing that happens is the processor
executes 'hlt'.

Interrupts are enabled on the next line, and I can verify that it works
here. ;) What type of system is it?
