Hello everyone, Could anyone explain to me how does serial driver suspend-resume work. How are the characters printed even if the system has gone to suspend with a special option called console_suspend_enabled. Are these stored somewhere and later displayed after resume. Or is the serial driver is not suspended if console_suspend_enabled. If so how is the processor going to sleep if serial controller is alive. How does all this work? How does one find a bug if there is a issue in suspend-resume. Are the debugging techniques listed somewhere. Thanks & Regards, ryan
