Comment 29 for bug 123789

Hello

After update from feisty (2.6.20-16.32-generic) to gutsy (2.6.22-14 generic), at first I could not boot.

Then I found out, that I have to trigger keyboard-events, for the boot-process to continue. It takes a minimum of about 15 times pressing shift and everytime waiting a second, to see, if something happens. Once KDE is loaded, I can use it almost normally, except that pressing and holding a key down, the repeat rate is awfully slow. In addition, all programs, all applications are affected, they just pause until I supply more keyboard-events: All cursors just stop blinking after a second, animated gifs in webpages only animate, as long as I move the mouse and stop moments later, video is jumping and hanging, if I don't do anything, animations in games hang, though they run perfectly smooth as long as I have a finger on the touchpad, even the simple clock screensaver is hanging (sometimes it invokes by itself minutes later, does a jump and two second ticks only to hang up again).

Without pressing any key and not touching the touchpad, I waited for the 2.6.22 kernel for an hour. After such a long time, I could not make it boot by pressing anything. On shutdown the same happens. if I don't move the mouse or press shift several times, the computer does not switch of.

The old 2.6.20 kernel works perfectly well. In bug #128617 I've posted some more details of my laptop Samsung r40 plus. The last comment also refers to this situation. I'll be happy to provide further details, just let me know.
