You mean when the system load is high? Yes, that can happen..

Has the external mouse ever worked in 2.6? Or is it always
just randomly clickng stuff? Have you tried connecting another
mouse?

I gather you do not have the X Synaptis driver installed?
Check out http://w1.894.telia.com/~u89404340/touchpad/index.html

Just to confirm - you are saying that the touchpad + external mouse
worked together fine in 2.4 but in 2.6 with i8042.nomux the external
mouse does not work, correct?

Ok, what program does the polling? What is the polling interval? Does
it help if you stop the program?

I see absolutely nothing wrong in the data stream from your external
mouse, so... how is it configured in X{Free86|org}? What type is it?
Does it work in text console (with GPM)? What is your GPM setup?

Try this - in the text console do:

gpm -k
gpm -m /dev/input/mice -t ps2

Try working the mouse, is it good?

Yeah, I figure there would not be any. Still I have a nagging suspicion
that the mux gets confused and I would like to see the full dmesg with
this patch applied and DEBUG enabled. Is there any change of getting it?

Actually, if you could change the patch so it would print not only data
but also str, like this:

printk(KERN_INFO "i8042.c: MUX reports error condition %02x (%02x)\n",
       data, str);

it would be even better.

Thanks!

Still don't have the initialization part... Is there any way you could
make your /var/log/messages file accessible via ftp or http?

Anyway, I also have a tiy patch to try out (attached, not tested/
not compiled). Please let me know how ifit makes any improvement.

Thank you.

You still need to use "dmesg -s 100000" even if you specifie logbuf_len.
Anyway, the data probably goes into /var/log/messages as well... If it is
there please send it my way (not on the list). I should be able to handle
100K e-mail.

Thanks,

Hmm... OK, I see that you have an active multiplexing controller.
I wonder if it gets reset back to legacy mode when you plug your
external keyboard. (btw, it it just a keyboard or a docking station/
port replicator?). Try passing i8042.nomux to the kernel and try using
your touchpad/keyboard. If nomux does not help you may try to use
psmouse.proto=bare or psmouse.proto=imps to disable Synaptics-specific
extensions.

Also, if you have time, please change #undef DEBUG to #define DEBUG in
drivers/input/serio/i8042.c, reboot, play a bit with touchpad; plug
external keyboard and send me output of "dmesg -s 100000".

Ok, we were getting reports about this happening with Toshibas, no

In May there was a posting Thorsten Hirsch and a patch reply by Dmitry 
Torokhov that did not help Thorsten.

I have exactely the same problem, and other people too. There's a thread on 
this topic with a more detailed problem description at:
http://www.linuxquestions.org/questions/showthread.php?s=&postid=1004645#post1004645

The problem was pested regarding to Kernel 2.6.6, but an upgrade to Kernel 
2.6.7 did not help me. My problem is even much worse:
 - The touchpad sometimes hangs and jumps.
 - Hitting on the touchpad does no more click the first button.
 - When I connect an external keyboard, the cursor somtimes jumps
   around like crazy and clicks around like fool, even if I don't
   click anything, but only move. When I then touch the keyboard,
   the mouse becomes normal for a while - on SuSE kernel 2.6.5,
   since. Since upgrade to kernel 2.6.7, does not become normal
   any more.
 - Sometimes the keyboard fails too, that means the without touching
   any key, a character is continually written, e.g. hundreds of "5"
   appear on the xterm. If i hit a key, a completely other character
   is printed, but not once but endlessly repeated.
 - Killing and restarting the X Server does not resolve the problem,
   reboot is the only thing that works!

It's really bad, I can't work anymore since I upgraded to SuSE 9.1 and kernel 
2.6...

Kernel messages:

A lot of during use of touch pad:
- psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
- psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 4

When using the external mouse and the mouse jumps around (repeated 2-3 times):
- atkbd.c: Spurious ACK on isa0060/serio0. Some program like XFree86, might be 
trying access hardware directly
- psmoouse.c: bad data from KBC - timeout


I'm not subscribed to the kernel mailing list due to the heavy traffic. Please 
CC me in your reply (marc dot waeckerlin at siemens dot com). Thank's.
