Hello,

I just test acpi and it appears to have behave properly. I would like to
know via a script that the machine has been resumed. Something like

echo -n disk /sys/power/state
waitresumed
continue with the script

The naive solution to wait until "echo -n disk /sys/power/state" returns do not work because it returns too quicly.

Do you mean "echo -n disk > /sys/power/state"? This works correctly for me with suspend to ram ("echo mem > /sys/power/state").
How much too fast does it return? What about using a sleep 1 after the echo call?

Really? It should not... it can not. When machine is suspended, script can't run...
