Thinkpad Keyboard nuttiness since 2.5.60 with power management

Thinkpad Keyboard nuttiness since 2.5.60 with power management

[Jerry Cooperstein]

Since 2.5.60 the keyboard on my Thinkpad 600X randomly
autorepeats each stroke multiple times, only when
power management is enabled (either APM or ACPI) and
only when powered up with no AC power.  With AC power
everything is fine, and pulling the plug out has
no effects.

Everything was fine in 2.5.59, and I can't find anything
in the 2.5.59->2.5.60 patch that could have caused this.
Anyone else see this -- or maybe I have a hardware problem
the patch is making visible?

Thanks

I am seeing a strange keyboard related issue as well on a Thinkpad A20M. It seems if I walk away for say, 20 minutes, come back and try to input a password to KDE's screen saver, the FIRST keystroke I make is not recognized at all. All keystrokes after the first one register perfectly fine. This is on the laptop's built-in keyboard. I too am using ACPI. If I don't wait long enough it doesn't happen, so I do believe it has something to do with power management. I first noticed it in 2.5.61(first 2.5 kernel that would boot for me) and am currently running 2.5.63, where I still see it. I am not using modules.

If anyone would like more info on this, please let me know.
