Okay, that seems to solve the "timer loosing time after resume" problem. But I still need to press some keys on suspend (7-12 key presses and releases) to unhang it. On resume not key presses are needed any more. During on suspend-resume cycle ACPI barfed afer resume spewing messages without end (error during execution of methode \...THM, error evaulation operand ...) I had to remove the battery and pull the power-plug to reboot it. BYtE Philipp -- / / (_)__ __ ____ __ Philipp Hahn / /__/ / _ \/ // /\ \/ / /____/_/_//_/\_,_/ /_/\_\ pmhahn@titan.lahn.de
