Maybe TTY changes? For completness, Andi sent me the following evtest output off-list yesterday. The LeftAlt being autorepeated at time 1246964430.448470 is a little bit suspicious, as it is preceeded by release ... I don't see how this could be causing the behavior Andi is observing though. I am not able to reproduce the problem myself.
