Hi.

Patch that I find at "
http://bugzilla.kernel.org/attachment.cgi?id=5599&action=view " does
not make any good thing. With this patch I still see log messages like
"Many lost ticks. Cheking if cpu frequency changed.." and "Touchpad
lost sync at byte N". And one strange thing against this patch:
keyboard lags too (I mean if for example "Q" is pressed and battery
state checked at same time I get
"qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq" in console)
With patch " 
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches
/release/2.6.13/acpi-20050729-2.6.13-rc6.diff.bz2
" I don't more see any messages at all, only one-second-freezes like
with clean rc6.

with this problem.

Touchpad goes crazy then programs like Kpowersave or Gkrellm check
battery state or current cpu frequency.

 With 2.6.11.4 in dmesg I see this:

psmouse.c: TouchPad at isa0060/serio4/input0 - driver resynched.
psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 4

With latest 2.6.13-rc5 kernel I get this:

warning: many lost ticks.
Your time source seems to be instable or some driver is
