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
