It was one of the things motivating the existence of the /sys/devices/.../power/wakeup attributes: we need to be able to work around broken hardware. - Dave ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
