I have HP nx6325. I've tried to use WARN_ON_ONCE patch, but I don't see
nothing special in dmesg. Just in case I'm posting my
dmesg_2.6.20_WARN_ON_ONCE_on_battery log on
http://bugzilla.kernel.org/show_bug.cgi?id=8235 .

Below I post output of my /proc interrupts (10 sec. delay between reads).

Other interesting thing on 2.6-git is that when I press a key on keyboard it
doesn't repeat (on battery), but it repeats on 2.6-git on ac.
