Comment (by tqh):
Maybe it is because we disable all but cpu 0 before shutdown:
{{{
// Make sure we run on the boot CPU (apparently needed for
some ACPI
// implementations)
_user_set_cpu_enabled(0, true);
for (int32 cpu = 1; cpu < smp_get_num_cpus(); cpu++) {
_user_set_cpu_enabled(cpu, false);
}
// TODO: must not be called from the idle thread!
thread_yield();
status = acpi->prepare_sleep_state(ACPI_POWER_STATE_OFF,
NULL, 0);
if (status == B_OK) {
//cpu_status state = disable_interrupts();
status =
acpi->enter_sleep_state(ACPI_POWER_STATE_OFF);
//restore_interrupts(state);
}
}}}
Inside {{{prepare_sleep_state}}} we hang.
