One new issue I see in 2.6.30 (I think I saw it in some rc*s) too is that console switch often leaks the Fkey of the console switch into the target console. The symptome is that e.g. firefox if it was active and you're switching into X displays its help screen (F1 = help). It happens on non X consoles too, but of course the symptoms are different here. That's a regression against 2.6.29; I don't remember it in .29 Haven't investigated code.Are you seeing with a specific keyboard type(s), or is this a general problem? Could you confirm whether it is specific either to PS2 or USB keyboards only, or it does happen for both?Can't think of any input chnages in this timeftrame that would cause such effect. 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.
