I noticed that sometimes I am getting "acpi: resumed at..." message on console and
in system log when I initiate system shutdown by pressing power button.
I think that the cause is in acpi_UserNotify("Resume") call and this call is only
found in acpi_EnterSleepState().
I see the following code in that function:
case ACPI_STATE_S5:
/*
* Shut down cleanly and power off. This will call us back through the
* shutdown handlers.
*/
shutdown_nice(RB_POWEROFF);
break;
So it seems that it is expected that shutdown_nice() would return immediately.
I think it makes S5 a special case comparing to other states where return happens
upon resuming from the state.
In this case, maybe it is not necessary for S5 request to go through the
resume/wakeup half of acpi_EnterSleepState.
