Oh yes, really!

Have you read my other bug report where I have mentioned that there is
a problem with ACPI and the keyboard unless I load the USB modules
(just in case you have not read the mail I add it at the end of this
one)? USB just make the problem to go away (may be erroneously).

Up to now every was compiled as modules. 

If I try to compile ACPI inside the kernel, I got:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

The Makefile for building the kernel seems to be missing a dependence
(no, no, I have not forgotten to emit "make dep" after configuring the 
kernel :-). As a workaround, I did:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----
cd drivers/pci
gcc -o gen-devlist gen-devlist.c
./gen-devlist <pci.ids
-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

Apparently, compiling ACPI in the kernel, fixes the problem I have with the
keyboard. I will investigate to test if it also fixes the problem 
with USB and SONYPI. I will tell you this by tomorrow morning.

Many thanks.

Hello there,

Here is the description of the second problem I have when running Linux
on my Sony Picturebook PCG-C1MHP. This time, it concerns the ACPI support.
I have actually two problems with ACPI. Let's start with the first one
(the most important one).

[1.] One line summary of the problem:
=====================================

Accessing ACPI files insert spurious characters in X's windows (such as Xterm,
Emacs, ...)

[2.] Full description of the problem/report:
============================================

ACPI works in the sense that it provides significant and relevant information.
Actually I'm using the following modules:

ospm_thermal (for proc temperature)
ospm_battery (for battery charge level)
ospm_ac_adapter (for checking if we are on/off-line)
ospm_bsmgr (which is, as far as I have understood used by the other modules)

Up to now every thing is fine, loading these modules enable access to
/proc/acpi/XXX/XXX/{status,info} files. Perfect. The problem is that 
reading any of these files has a very cumbersome effect. It seems to
generate interruptions that act as key press. The consequence is that
if simultaneously you access a /proc/acpi/XXXX file and you move the mouse
over an Xterm or an Emacs window, the window is filled out with random
characters! The best way to illustrate the problem is by running a loop
such as:

while : ; do 
  cat /proc/acpi/ac_adapter/0/status
done

and then moving the mouse over and Xterm. Each time we move the mouse, each
time a new random character is displayed. 

In addition to my previous shell loop, I run in another Xterm the following:

while : ; do
  cat /proc/interrupts
done

This last file shows:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

That is, my impression is that each time I access the /proc/acpi/XXX files,
the keyboard interrupt counter is incremented!

Now let's go to the real strange thing. If in addition to the previously
loaded modules (the ones describe in section 7.3 above), I load the two
additional modules: usbcore and usb-ohci the problem totally disappear! 
That is, when loading these two additional modules, accessing the /proc/acpi
files and moving the mouse simultaneously does not introduce spurious
characters anymore!

You could think that, loading the two additional modules is a simple 
workaround... Well actually it is but, loading the two usb modules introduce,
in turn, new problems that I will describe in a next bug report...

One more time, many thanks for your help. As I have said in my previous

ps: I have noticed the same problem with all the kernel version I have tried
(2.4.19, 2.4.20pre10, 2.4.20rc1, 2.4.10pre10-ac2)
