OK, so recap what should be tested:
1) "echo core > /sys/power/pm_test
powersave -u (btw. my debian box doesn't have this - what is the equivalent?
- simple suspend to ram?)
2) check whether acpi_power_off_prepare is called during poweroff
diff --git a/drivers/acpi/sleep.c b/drivers/acpi/sleep.c
index 3fb4bde..0fab34e 100644
--- a/drivers/acpi/sleep.c
+++ b/drivers/acpi/sleep.c
@@ -685,6 +685,8 @@ static void acpi_power_off_prepare(void)

acpi_sleep_prepare(ACPI_STATE_S5);
acpi_disable_all_gpes();

+ while (1) cpu_relax();
}
static void acpi_power_off(void)
3) try patch from comment 22
4) try patch from comment 23 if 3) fails
Is that correct?
