2.6.34-rc3++ looses PS2 keyboard eventually in xterms

2.6.34-rc3++ looses PS2 keyboard eventually in xterms

[Hans-Peter Jansen]

Hi,

after switching to 2.6.34-rc3 with follow ups added up to 5e11611a (e.g. 
including the tty fix), I still suffer from "loosing" my PS2 keyboard 
eventually during work in xterms (which I do use a lot). Everything else, 
ssh'ing from remotes, mouse operations, even mouse clicks into xterms is 
still functional, e.g. I'm able to quit htop by clicking on F10. Just every 
direct keyboard input is lost, without a trace in syslog, as well as 
Alt-SysReq sequences. echo r > /proc/sysrq-trigger doesn't show any effects 
either. AFAICT, it doesn't happen with older kernels (2.6.33.2/2.6.27.y). 

OS/Hardware:
openSUSE 11.1/i586, KDE3, ASUS P7P55-WS, Xeon X3460, 4 GB.

Any hint on how to debug such an issue is much appreciated.

Thanks,
Pete

Correction: 2.6.33.2 is affected as well. Problem is, I don't know a 
procedure, that reproduces the issue reliable, thus bisecting is not an 
option.

sysrq triggered process and lock state trace (when the keyboard was "lost") 
is available here: ftp://urpla.net/xrated-kbd-lockup

Dmitry, I've CC'ed you, since you seems the premier guy for input related 
issues. Do you have an idea? I guess, that my hardware setup isn't that 
uncommon, my keyboard is a "solid as a rock" Cherry G80, btw.
