Wysocki" Hi, I am asking everyone to give this patch a try. It is reported to speed up suspend process, however there is a risk that there are boxes out there that do require full reset and I would prefer to know that sooner than later. Thanks! -- Dmitry Input: speed up suspend/shutdown for PS/2 mice and keyboards Instead of doing full-blown reset while suspending or shutting down the box use lighter form of reset that should take less time.
