Infinite loop of Xf86battery key presses

[Sympy]

Binary package hint: gnome-power-manager

I have Intrepid installed on a Dell Vostro 1400.

Pressing Fn+F3, the battery button, had no effect until recently, when Bug 281134 was
fixed. Now, it starts an infinite loop of key presses that opens a neverending sequence
of battery popups. This eventually hangs my system and forces me to reboot.

Though I'm reporting this against gnome-power-manager, I've confirmed that xev in
fact reports a loop of Xf86battery key presses, so g-p-m is just doing its job. But I
didn't know where exactly I should report this against.

Thank you for your bug report. I suspect this is related to missing key release events from the kernel, and nothing to do with gnome-power-manager. Could you please switch to a console (CTRL+ALT+F1), run "showkey -s", press your battery key and tell me what you see?

Thanks

Chris,

Running "showkey -s" and then pressing Fn+F3 gave me "0xe0 0x71".
Then I just waited the 10 seconds for the program to finish.

When I returned to X, I ran xev just to make sure that infinite loop
wasn't running on background. Apparently, it wasn't.

One interesting thing: xev accuses the same infinite loop for Fn+F1
(Xf86standby). I didn't notice this before because it has no effect
(perhaps it suffers from the same bug that was recently fixed for
Xf86battery? I can open a new report for that...)

This affects my XPS M1530 as well. There appears to be a kernel patch for this..

These are the links to the two patches which need to be applied to atkbd.c:
