 It seems I can write CDs on my laptop now. AFAICR I was last trying it on
test8, but it was the same: if the image is over ~400Mb, the machine
freezes hard. If it's shorter, then it's ok, but still some lock or sth
is not unlocked, as the CPU is used more and more about five secs by one
or two percent. Sooner or later it's crashed as well, but I could
restart the machine before that happened. Rebooting to 2.4.2x and
writing CDs there was working all the time.
 So I do not know if it's fixed since test8, or in 2.6.0-mm1, but I am
happy with it. Also, I have two problems with 2.6.0-mm1:
- I can not deselect CONFIG_SCSI, only module or built-in available.
  Maybe something is depend on it, but could not figure out what (no
  CONFIG_BLK_DEV_IDESCSI, nothing is selected under CONFIG_SCSI).
- I have a synaptics touchpad, which is detected correctly, but only
  works if I set psmouse_noext=1. Under vanilla 2.6.0 it still works this
  way, but with 2.6.0-mm1 it works only on the console, but not under
  XFree86. Strange, as gpm interprets the input and pipes thru gpmdata
  to XFree86 4.3.0. Any idea what broke this configuration?

Yes, this part of the config system is hard.  It always has been.  It's
similar to "wtf do I have to enable to make the <foo> menu appear.

I bit of grepping tells us that CONFIG_USB_STORAGE turns on CONFIG_SCSI.

 Thanks! Never throught. I could come up with this:
find . -name Kconfig| xargs grep --colour 'depends.* SCSI'
(Execute in the kernel tree, and replace SCSI with whatever you like;
may help others with similar questions).

> Peter or Dmitry may be able to tell us.
 IMHO it's either:
serio-04-synaptics-cleanup.patch
serio-06-synaptics-use-reconnect.patch
synaptics-powerpro-fix.patch
serio-pm-fix.patch
input-02-add-psmouse_proto.patch (?)
input-05-psmouse-fixes.patch
input-07-remove-synaptics-config-option.patch (maybe?)
input-08-synaptics-protocol-discovery.patch

Thus meanwhile I try to revert them. Anyway, as -mm1 is already bigger,
is it possible that you release 2.6.1 in this year with some/most of the
fixes in mm1?

 Just found out psmouse_noext is deprecated. I have specified
psmouse_proto then, but imps and exps (and bare too, but I have not
tested it, as reading the code it seems psmouse_noext falls back to
bare) are the same. On the console touchpad is working, under XFree86
4.3.0 is not. To be more specific, the buttons do work, but I can not
move the pointer at all. Well, first I thought the middle two buttons
are for scrolling, as they are placed (and IIRC, they do scroll under
m$ win), but the top button is like the left button and the bottom button
is for paste, ie middle button on three buttons mices.

May we see your dmegs, XF86Config and the parameters you are passing
to GPM please? Btw, what version of GPM are you using?

As far as reverting patches I would start with
input-08-synaptics-protocol-discovery.patch

The Synaptics driver used is 0.12.2, compiled for myself, evdev is in
module, but ofcourse it's loaded before XFree86 starts. (I have stripped
down the files a bit, if you would like to see the whole files or other
parts, please ask - I thought it would be easier to see the relevant
lines only). gpm is configured by /etc/gpm.conf , but it should be:
gpm -m /dev/psaux -t ps2 -R raw
Also, the XFree86 Synaptics driver prints this while starting and
switching between console and XFree86:
Synaptics DeviceInit called
SynapticsCtrl called.
Synaptics DeviceOn called
Synaptics DeviceOff called
[the last two repeated more times]

> Btw, what version of GPM are you using?
 I am running Debian Sid, thus I also thought gpm is the newest; as I
do understand I should use 1.20.1, which is the latest AFAIK. Thus I was
shocked a bit on what 'dpkg -l gpm' gives:
ii  gpm            1.19.6-12.1    General Purpose Mouse Interface
More than a year old! Already filed an important bug on this. Sorry, it
seems to be the problem, or at least produces strange behavior:
I plugged in an USB mouse, which works while the touchpad still not
under XFree86 (both works at the same time under console - even if I did
not specified any additional config for gpm). The config for XFree86:
-- XF86Config-4 --
Section "InputDevice"
        Identifier      "USB Mouse"
        Driver          "mouse"

        Option          "Device"                "/dev/input/mice"

        Option          "ZAxisMapping"          "4 5"
EndSection
-- XF86Config-4 --

Made it the only one pointer input. Now, if I kill gpm with 'gpm -k',
then the touchpad begins to work! Sometimes if I release it, then the
pointer jumps a bit from where I pointed it, but that's all. I'm not
good in mice stuff, so I can't explain this. Anyway, I will try to
compile a newer gpm, change it's device, so play a bit; maybe I can come
up with something.

On the other hand, the synaptics touchpad on my laptop works under 
2.6.0-mm1 without the need to use the above parameter.  I don't get the 
jitter I reported for vanilla 2.6.0 synaptics support, but I do get an 
occasional small mouse jump.  

Other than that, 2.6.0-mm1 appears to be working well on my Presario 
12XL325 laptop.

Whew.. that wasn't easy to spot... When doing PS/2 emulation for touchpads
that use absolute events, when processing BTN_TOUCH event mousedev would
stop on the very first client. So in your normal case only GPM would see
the Synaptics but once you killed GPM XFree would be the first in line and
magically start working.

My guess you didn't see that in stock 2.6.0 because you were compiling
without Synaptics support.

I am sending 2 patches - one to remove mouse jitter with Synaptics when
it is used through mousedev (PS/2 emulation) - mousedev will use 3 point
history and average when calculating deltas, the other one is the fix for
the problem you are experiencing. They should apply to 2.6.0-mm1 and to
stock 2.6.0 with minimal jitter.

Synaptics problems in -mm1

[Tomas Szepe]

Hi,

it seems one of the synaptics-related patches in 2.6.0-mm1 kills
off the pointer stick on my T40p.  2.6.0 vanilla works just fine
in that department.  Thought you might want to know.

Reverting

	input-08-synaptics-protocol-discovery.patch
	input-07-remove-synaptics-config-option.patch
	synaptics-powerpro-fix.patch

did not seem to help.  I failed to figure out a way to easily revert

	serio-06-synaptics-use-reconnect.patch
	serio-04-synaptics-cleanup.patch

so that I didn't try.

 I had the same problems, but Dmitry provided two additional patches,
which made my one working. Have you tried them? You can find them in the

Unfortunately, the two patches from this thread don't solve
the mm1 problem I'm seeing, the stick keeps on resting. :)

I have a couple of questions (I am not familiar with IBM hardware so
please bear with me...):
- Is it detected as Synaptics but does not work?
- Should it be detected as Synaptics?
- Does it work if you pass psmouse_noext=1 or psmouse_proto=bare?
  And what about psmouse_proto=imps and psmouse_proto=exps
- Does it work if you give 2.6.0-test10-mm1 a quick boot?
- dmesg, input section of you XFree and version and parameters that
  are passed to GPM.

Thank you,

No problem.

There are two pointer controllers on the T40p: a stick and a pad.
With 2.6.0, just compiling in synaptics support and running gpm as
"gpm -t ps2 -m /dev/psaux" or XFree with

  Option          "Protocol"      "PS/2"
  Option          "Device"        "/dev/psaux"

gives perfect results, both controllers work, even with
all the (3 + 2) buttons.

With 2.6.0-mm1 (the same .config of course), however, the stick does nothing.

Ok, are you running with cpufreq? I think it ACPI PM timer if you have
it activated - I am having problems with it myself but didn't have time
to look closer. Could you try booting with clock=tsc or clock=pit and
see if it fixes the touchpad.

Yes, but
	1) I've been on AC all the time.
	2) 2.6.0 works.

clock=tsc		appears to fix the problem.
clock=pit		no change.

Well, I have a daemon that monitors load and dynamically switches
between high and low frequency...

Ok, good. So it is the timer funkiness. I would suggest not using ACPI
PM timer for now then. And yes, timer_pit does not have cpufreq hooks
either so it probably not the best timesource with cpufreq either,
so stick with TSC.

Sure, I've got one, too, but configured it to always go full throttle
when on AC.

Stupid me, I absolutely forgot that I had enabled CONFIG_X86_PM_TIMER
(nonexistent in 2.6.0 stock) which indeed seems to be the culprit.
Please accept my apologies.  -mm1 with that config option unset won't
lose the stick, either.

Thanks!

So we've established that it is an interaction between the input code, the
ACPI PM time code and cpufreq, yes?  That's a bit of a witches brew.

Does anyone know what aspect of the ACPI PM timer behaviour could cause
this?

At least psmouse times out much quicker than 4 seconds when resetting
the touchpad which causes many problems.

Looking at the PM timer was on my TODO list ever since it was included
in -mm... I tried installing cpufreq handler to do the same adjustments
for loops_per_jiffy as in timer_pit but I was still getting pretty much
the same result - time goes too quickly.

Ok, I have verified this witch is not _that_ cunning.  cpufreq actually
seems to be innocent, I am able to reproduce the problem with CONFIG_CPU_FREQ
unset.

Mousedev PS/2 emulation for touchpads in absolute mode does not support
taps. You will either have to use Peter Osterlund's XFree86 driver at:
http://w1.894.telia.com/~u89404340/touchpad/index.html
and an updated version of GPM at http://www.geocities.com/dt_or/gpm
or disable native Synaptics support using psmouse_proto option
(bare, imps or exps; any of them should do the trick).

 I have applied both to 2.6.0-mm1. They are just working, no jumping
mouse pointer when I release the touchpad, and both touchpad+usb mouse
working on console and under XFree86 as well. OK, I could not really
understand how they are working, as for me it seems gpm interprets
/dev/psaux only, and get both pointing device right, still XFree86 which
reads data replicated by gpm via gpmdata can't handle the USB mouse
directly. I had to use a separate config, which reads /dev/input/mice as
well. I think it's because XFree86's synaptics driver skip events from
the USB mouse. Anyway, thanks for your help and work!

 Update: I could trigger this bug in 2.6.0-mm1 as well with the Linux
port of Head over Heels (classic game from C64). The CPU was getting
more and more used, so the game slowed down. I could quit then from the
game and XFree86. I did an emergency sync, and it succeded. Issued halt,
but it stopped at init sending term to all processes, so I tried a hard
power off. I got an error, something about slab, maybe at line 168. It
was scrolled out too fast by the stack-trace, and at the end:
ACPI-0094: *** Error: Could not acquire interpreter mutex
Crashed there. :-(
