Thanks for your report. Assuming that the code responsible for
registering the suspend operations is drivers/acpi/sleep.c for your
platform, and that acpi_sleep_suspend_setup() iterated over all possible
sleep states, your platform must somehow be returning that ACPI_STATE_S3
is not a supported state somehow?

Rafael have you ever encountered something like that?
