Touchpad problem on 15XX Acer Aspire laptops.

Touchpad problem on 15XX Acer Aspire laptops.

[Dmitrij Bogush]

Hi.

Someone Dmitry Torokhov on LKML told me to contact ACPI mailing list
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 hogging interupts
rip handler_IRQ_event+0x20/0x60
 
With 2.6.13-rc5 touchpad freezes for a second, do not goese crazy like
with 2.6.11.

Thanks.

Please test linux-2.6.13-rc6 with patch filed at bug 3851 , Please try both
ec_burst=0 and ec_burst=1.

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.

[Yu, Luming]
