Sorry I do not know about the issue accurately now because I am not using my N900 anymore. But I think that it sometimes rebooted or that you had to unplug your cable while the N900 stucks at the 'Nokia' logo to boot it up or something like that. I also didn't remove kernel power due to the features and had to accept this issue. It was just annoying that you were not able to reboot your device anymore. Also check this thread where I noticed this issue (KP v48): here (http://talk.maemo.org/showthread.php...07#post1088907) I mentioned the problem and the discussion started here (http://talk.maemo.org/showthread.php...16#post1120716).
