Description Felix Schuster 2006-02-19 10:01:38 UTC
Most recent kernel where this bug did not occur: There's no one

Distribution: Gentoo 2005.1

Hardware Environment: Gericom Overdose Laptop

Software Environment: Linux laptop2 2.6.15.1 #3 PREEMPT Mon Feb 13 16:15:57 UTC
2006 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux with Gentoo, X,...

Problem Description: Now and then the touchpad stops working correctly. You can
move around, but clicking has no effect.
The error message is: psmouse.c: bad data from KBC - timeout bad parity
This message appears about 100x times in the error log.

Steps to reproduce:
I haven't recognized important facts which have to occure.
It happens often, when mozilla web browser is started (but not sure, if it's
related to this)

I searched the web a lot. And I found some other people having the same problem.
But no one posted a solution for that. I think there is a big connection to the
"psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1" problem.
Probably the synaptics drivers are also related to.

Comment 2 Vojtech Pavlik 2006-03-04 01:39:07 UTC
This is most likely a hardware bug (bad mouse cable for example). What hardware
and kernel combinations did you test?
Comment 3 Felix Schuster 2006-03-05 08:48:52 UTC
I can not imagine that this is a hardware related problem. I am guessing it is a
driver bug.
I am using a touchpad and I get this error. It happens with every kernel I had
(>= 2.6.12). I had windows before. There was the same problem.
I can not understand why the mouse begins to jump around and clicks anywhere.
When a message like "throwing x bytes away" appears, the mouse should stay there
(in my opinion) and should wait for the next input.
Comment 4 Vojtech Pavlik 2006-03-05 14:29:29 UTC
Using 'psmouse.rate=40' on the kernel command line might help. Can you try that?
Comment 5 Felix Schuster 2006-03-05 14:54:11 UTC
I'll give it a try. Because it is not a reproducable bug (it happens randomly) I
can tell you in a few weeks, if this works.
For my information: What's the default for psmouse.rate?
Comment 6 Dmitry Torokhov 2006-03-05 15:20:58 UTC
I don't think psmouse.rate=40 will help - Felix does not have Synaptics 
touchpad but a Logitech one (there was a but in psmouse - it was not setting 
the "name" and so <NULL> was printing in the logs). 
 
Just to confirm - you said you were having the similar problem with mouse in 
windows, right? How often does this happen?   
Comment 7 Felix Schuster 2006-03-05 15:48:36 UTC
I have a touchpad (think noname touchpad, laptop is a Gericom one), can't
imagine that it is from Logitech. Did you mean Yauhens comment (with <NULL>)?
The problem occurs in windows as often as it does in Linux. It happens
uncommonly, there are weeks without any problems. And then it occurs a few days
again and again.
Comment 8 Vojtech Pavlik 2006-03-06 00:18:40 UTC
Don't be surprised if the touchpad is Logitech: There are only Logitech, Synaptics
and ALPS touchpads, so it's got to be one of them.

Regarding the psmouse.rate=40, the default is 100, and I also don't expect it'll
help, but the messages from the i8042 KBC mean that it's getting garbage (not
even valid bytes) on input.

This can result from
            a) Bad cable or loose connector. 
            b) Overloaded firmware in the KBC

The psmouse.rate should solve b). For a), which I believe is the most likely
option, especially because it's unlikely to be a driver problem if it happens
under Windows as well - Windows has completely different drivers and are tested
by the manufacturer to work with the pad - I'd suggest disassembling the
machine and reseating the touchpad connector to the mainboard. I've seen loose
connectors cause similar  intermittent trouble in the past.
Comment 9 Felix Schuster 2006-03-19 12:57:39 UTC
So here I am back again:
I tried to fix this bug with the psmouse.rate=40 kernel parameter.
Till yesterday it worked ;) So this means Vojtech appears to be right (never
doubt him). Perhaps the parameter scaled down the cases - but I can't imagine.
Comment 10 Dmitry Torokhov 2006-04-04 13:39:46 UTC
You are right, I should never doubt Vojtech ;)

So could you tell me what model you touchpad is? Is it identified as Synaptics 
by the kernel? If so please send me output of "dmidecode" utility.

Thanks!
Comment 11 mike 2006-04-21 12:45:33 UTC
Hi guys, I have had this same error psmouse.c: bad data from KBC - bad parity.
I have tracked this down to an ESD problem. I know it sounds far fetched but I'm
using a HP dv1133 laptop. It is dual boot and I experiance lockups in windows
and this error in Debian with kernel 2.6. I started noticing that the problem
would start after I set the laptop down and came back to it and zapping it with
an ESD.
Just to confirm my hunch I installed a wrist strap and grouneded it securly. 
Now I'm able to reproduce without fail... no wrist strap intemitant lock-ups,
with strap never failed.
Also I have noticed that if I am running on BAT power and not AC the lock-ups
were  less of a problem. I suspect that when I'm on AC the laptop is grounded
and I got a better strike on it. 

Hope this helps.

I'm getting a ton of:

Immediately after booting my HP dv8000 laptop. FC5 with 2.6.18 kernel. Just
started happening after updating to 2.6.18smp. I don't think I saw it before that.
Comment 13 Felix Schuster 2007-01-05 03:15:23 UTC

No, how can I find this out?

I don't think so, but maybe I am wrong. Is there someone who can tell me, how to
find this out?

Felix, have you tried new kernel lately? Is the problem still there?
Thanks.
Comment 17 Felix Schuster 2007-06-23 03:04:42 UTC
I still had this problem with 2.6.18.6, currently I am running 2.6.20.7. I recently did the update, so Iifear it will happen again.
Do you want me to try 2.6.21.5 as it is the newest stable kernel (kernel.org)?
Comment 18 Natalie Protasevich 2007-06-23 03:30:32 UTC
I'd say try the latest pre-released, 2.6.22-rc5 as of now. New fixes usually go to -mm, so if there was a fix submitted to your problem, you'd have to test latest -mm. Reason to test anyway is because sometimes problems get fixed indirectly.
If the new kernel fails, please go carefully through #14.
Comment 19 Paul Roy 2007-06-27 16:23:08 UTC
hey .. Ive got an LG T1 laptop with the same problem. Odd thing is, from looking at /var/log/kernel.log, I can see that it was in fact loading the proper Synaptics modules/driver on the 1st few boots, but then it switched to "PS/2 mouse" and I had psmouse.c bad data problems from there.

Whats stranger still however, is that now since this morning I cant even get ps/2 mouse ! .. it loads NOTHINGS, and /proc/bus/input/devices lists no mouse anymore. I HAVE to connect an external mouse.. 

Now, its something I do anyway cause I dont really enjoy touchpads, but it really bugs me to think maybe this 1500$ machine I bought last week has a hardware problem .. ..
Comment 20 Paul Roy 2007-06-27 16:26:36 UTC
to follow up on that last comment of mine (#19) - I have to say I think I remember the mouse acting up in the moments following the loss ... I didnt pay too much attention to it as I was "crouched down, hodling my laptop with one hand trying to type in commands with the other", cause my friend's ethernet cable didnt reach far enough for me to leave it on his desktop... so i just assumed I was somehow touching the mousepad by accident while typing in such a precarious position .. Then I loaded entrance, the e17 login manager, and all that is e17 related is very  alpha as everyone knows, so the non responding touchpad didnt concern me too much as I thought it was an entrance related bug. Its when it didnt work in either kde, icewm, or just plain X with nothing loaded but xterm, that I got worried ...
Comment 21 Dmitry Torokhov 2007-06-27 20:26:29 UTC
Paul,

I think in your case the touchpad connector got loose and disconnected. It is usually easily fixable.
Comment 22 Paul Roy 2007-08-15 08:42:57 UTC
hello. I would have another question since you seem to know a bit more
than I do regarding such matters. First of all, what is the kbc bios
and what does it have to do with my touchpad ?

I mention this because I have been having an intermitent display
problem which seems related to my video bios or some firmware issue.
(this is just a hunch). Basically its as though my laptop does not
recognize it's LCD display and sends it the wrong "signal" - and
evertyhing on the screen looks distorted and interlaced, in any video
mode. Further more, when I boot up all the way, I find the display's
native resolution of 1440x900 is not available. I use 915resolution,
could that have consequences on my video bios ? Then again I thought
maybe the fact the touchpad mouse wasnt responding was confusing the
laptop in a way and screwing my display. Like I said, its intermitent,
and impossible to reproduce.. I have no clue whatsoever as to what
might trigger the problem. Hitting ctrl-alt-del a few times usually
does it, as it ends up usually getting the right display. I have
noticed differences in xorg.0.log as well as outputs from lshwd, lsdev
and lsmod between the two "states"...

so i guess my question is what is kbc bios and does it have anything
to do with it ?

Comment 23 Edward Macfarlane Smith 2007-08-19 06:12:53 UTC
I've been having problems with this error too (On a Sony Vaio VGN-SZ3VWP which I believe has an alps touchpad), running SUSE 10.2. I've upgraded through various kernels, currently on 2.6.22.1. I just tried adding the psmouse.rate=40, it hasn't got rid of the problem completely (I still sometimes see the message in dmesg), but does seem to have significantly improved things (though maybe I'm just being lucky for now!).
Comment 24 Felix Schuster 2007-08-28 10:31:40 UTC
I tried kernel-2.6.22-rc4-mm2 over the last two month. The problem seems to be
solved, it never happened again. Currently I am running 2.6.22.1, i haven't recognized this problem yet.
Comment 25 Felix Schuster 2007-09-17 15:36:45 UTC
2.6.22.1 is vulnerable too.
going to test an mm version further
Comment 26 Felix Schuster 2007-09-17 15:37:45 UTC
btw: updated kernel version in the bug details
Comment 27 Natalie Protasevich 2007-09-17 21:33:54 UTC
Thanks, please keep us posted.
Comment 28 Yurij Mikhassiak 2008-07-21 02:44:45 UTC
Hi. The same problem!
 - bad parity

It's happen in Linux Mint based on Ubuntu 8.04 (life CD too)
Synaptic touchpad on Compaq Evo n410c stop responding after 1-9 minutes of using it..
Kernel loads modules for touchpap and PC/2 mouse (using just touchpad)
In doal boot windows Xp everything works Ok 
the other problem I see is that in time of system start loading stops for 20 sec. when loading drivers and go again.
What can I do?
Comment 29 Andres Mujica Ubuntu BugSquad 2008-08-10 18:30:27 UTC
Hi all, i've linked the LP #119194 with this bug as it seems these are the same
one,

Comment 30 Matt Lapaglia 2008-10-07 21:29:31 UTC
I am also still having this issue on Ubuntu Intrepid with 2.6.27-6-generic kernel on a Compal hel80 laptop. I've had this issue since Gutsy as well. It always happens directly after login, i receive the same error messages as the original poster.
Comment 31 Harlan Lieberman-Berg 2009-04-19 09:24:18 UTC
This issue is still happening (or a similar form of it) in 2.6.27.21.

I will attach the relevant portions of dmesg.  Please note, I have tried the psmouse.resetafter=1 option, and although it appears to provide some relief, it is always temporary.  Once the behavior starts, it will rapidly occur more and more often until finally the mouse stops moving and responding to clicks altogether.

I am happy to provide more information as you request it.

Comment 33 Harlan Lieberman-Berg 2009-04-22 00:28:16 UTC
On the most recent boot, I had a new error message.

alps.c: Failed to enable hardware tapping.

Is the consensus that this is a hardware problem still the same one? Would that error be indicative of a hardware failure, or does this indicate the problem might be a driver?
Comment 34 dk 2009-06-07 18:13:39 UTC
I have encounter the same problem when 'pre FC11' was installed. It makes xwindows almost unusable as the mouse cursor seems to either hang or gone crazy and randomly clicking things.

I have been using Linux for a long time (since kernel 1.2.8 - good old day of slackware) and this is the first time ever happens

A fix seems to be included when I tried to update all packages, however this still happen (rarely) Here is the log (/var/log/messages)

Comment 36 Damjan Jovanovic 2009-11-08 13:50:58 UTC
This bug is an ancient regression; I think 2.6.4 or 2.6.5 was the last good version. Back then the kernel still complained, but the mouse didn't go crazy like afterwards. Please regression test and fix.
Comment 37 Damjan Jovanovic 2009-11-11 06:12:28 UTC
Hi all

I've found the problem. This bug really is a regression. The last good kernel version was 2.6.1, the following patch in 2.6.2 that added parity checking introduced the regression:

Commenting out that entire parity check if block fixes the problem in 2.6.2.

I've also noticed that there is a lot of time - 4 seconds - between the kernel printing "psmouse.c: bad data from KBC - bad parity" and the subsequent "psmouse.c: Wheel Mouse at ... lost synchronization, throwing 3 bytes away".

Maybe the mouse jumps around and clicks like crazy during those 4 seconds because the kernel wrongly believes it is still synchronized when it actually isn't, so the protocol is parsing rubbish data?

Maybe when we have a parity error, we should resynchronize immediately?

patch to resync when we get bad parity from the mouse

Hi

So I made a patch to resync the mouse on bad parity like I suggested, and it seems to work well - the mouse no longer jumps around and clicks. It does however freeze up momentarily (for about 200 milliseconds) instead. The new output is:

[ 2630.187651] psmouse.c: bad data from KBC - bad parity
[ 2630.196228] psmouse.c: resync failed, issuing reconnect request
[ 2630.340598] psmouse serio1: ID: 14 00 64

I'd appreciate some comments from those who know the PS/2 mouse code?

Thank you

Hey! Can you do something to output error datails to user? 99% of them even
don't know were to find system logs and how to do this without mouse or
aspacially touchpad..I understand it's not a kernel level problem but we
have do do something for ordinary users..

Possible message could be: "kernel reported the pointing device error. Bad
paryty. Try to reconnect or change pointing device due to the possible
hardware failture" and give possibility to open system log from dialog.

This is not kernel's task. There are programs that monitor kernel logs (kerneloops comes to mind) and alert user.

We can't simply ignore parity errors. ON reasonable hardware parity error means that the transmitted byte is damaged and should not be trusted.

I wonder why the resync fails and you need full reconect. Could youplease try reproducing the condition with i8042.debug and posting the dmesg? Also, what kind of box and mouse is that?

Thanks.

Box is a PC, which works fine with another PS/2 mouse.

Mouse is an unbranded $5 2 button ImPS/2 optical wheelmouse that also breaks on other boxes running Linux >= 2.6.2, and works perfectly fine on every version of Windows.

I don't see anything from i8042, probably your syslog redirects kernel.debug somewhere else?

Comment 48 Damjan Jovanovic 2009-11-24 13:40:32 UTC
Dmitry, please look at the dmesg (http://bugzilla.kernel.org/attachment.cgi?id=23751), search for "bad parity" and follow from there.

It seems we get a bad parity, my patch issues a resync, several interrupts later there's another bad parity, then eventually psmouse-base.c issues a reconnect request.

Any suggestions?

Comment 50 Vojtech Pavlik 2010-02-23 10:43:12 UTC
When we receive a bad parity byte, it may still make sense to notify the psmouse driver that a byte has been received, to allow it to discard the whole packet without getting out of sync. It would require some more logic in the psmouse driver, but might be worth it, the result would be a more or less smoothly working mouse.

Btw, we could try sending '0xfe' to the mouse, to force it to resend the last byte and/or packet, too, although that could get fairly complicated.

patch to discard the entire packet on bad parity

Thank you Vojtech.

The attached patch does what you describe ("notify the psmouse driver that a byte has been received, to allow it to discard the whole packet without getting out of sync.").

I still get bad parity messages in the log, but the mouse now works perfectly :-).

Should I patch all 8 protocol_handler functions similarly or is the psmouse_process_byte function enough? Any other comments?

Thank you
Damjan
Comment 52 Vojtech Pavlik 2010-03-02 10:02:26 UTC
The patch looks good to me, but please work with Dmitry to get that included in the mainline psmouse driver. He'll be able to tell you how to best integrate it in the driver so that it works with all the different protocols.

    Input: psmouse - ignore parity error for basic protocols
    
    Observing behavior of the other OS it appears that parity errors reported
    by the keyboard controller are being ignored and the data is processed
    as usual. Let's do the same for standard PS/2 protocols (bare, Intellimouse
    and Intellimouse Explorer) to provide better compatibility. Thsi should fix

This problem seems to still be alive (or at least a similar, related issue is still there).  Some info about my system is:

Distribution:  Mageia 1.

Hardware Environment:  HP Compaq nx6320 with docking station (EN488AA).

Mouse:  Logitech M-CAA43 (PS/2 attached to docking station)

Software Environment:  Linux localhost.localdomain 2.6.38.7-desktop-1.mga #1 SMP Sun May 22 11:37:00 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux


Steps to reproduce:

This is 100% reproducible, and there are three ways of triggering this:
1)  Boot laptop docked to the EN488AA, but with the mouse not plugged in.  Then once booted, plug in the mouse.  psmouse.c then fails 100%.
2)  Boot laptop docked to the EN488AA with the mouse plugged in (it will be functional).  Suspend and then come back up.  psmouse.c then fails 100%.
3)  Boot laptop docked to the EN488AA with the mouse plugged in (it will be functional).  Remove laptop from dock and then put it back.  psmouse.c then fails 100%.

Some of the error messages from dmesg are:

The original problem was about bad parity, and its fix solved that. Yours is a timeout, preceded by "Failed to enable mouse". Please open a different bug.
