Actually, since ACPI does explicitely require that interrupts are off at some point during state transitions, basically all code reachable by the AML interpreter must be safe to be run without interrupts. Btw, it might also make sense to avoid tsleep et al while DDB is active. A context switch while the other CPU is in the DDB loop doesn't lead to anything. best regards Matthias ------------------------------------------------------------------- ------------------------------------------------------------------- Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
