I did a bit more troubleshooting.
When I boot with a "recovery mode" kernel, for example:

kernel /vmlinuz-2.6.17-10-386 root=/dev/md1 ro single

the problem does not appear.

When I boot with a fresh compiled plain vanilla kernel, straight from kernel.org, the problem is also there. This rules out any debian- or ubuntu-specific patches to the kernel. So it's either a standard kernel problem, or it's something completely unrelated.

I took a deep breath, made a good backup, and upgraded to Edgy. I don't want to jump to conclusions, but it appears that the keyboard issue is gone. This message is the longest text that I have typed in about two months (!) without double and triple checking every keypress. It took me about 2 minutes (including looking up that line in /boot/grub/menu.lst) when before it would have taken me over 15 minutes.

I can confirm this bug!

See also #bug 63147

I have the same problem.
After a while keyboard gets unresponsive.
A workaround seems to be to unload and reload the usb module:
sudo modprobe -r uhci_hci;sudo modprobe uhci_hci

After that keyboard seems to work normally for a while.

I had the same issues, but the problem ist gone since I replaced the kernel module for my onboard ethernet controller [lspci: Intel Corporation 82557/8/9 [Ethernet Pro 100] (rev 08)] e100 (intel driver) by eepro100 (community driver). I'm not sure if this is a solution for everyone, but I realized, that the problems always occured during downloads or other network traffic.

On 15/10 I reported that the problem appeared to be gon when upgrading to Edgy.
Edgy is running smooth, and I haven't had any keyboard problems in 3 weeks.
So as far as I am concerned, the problem is solved and this bug report can be closed.

I have still the problem, also with edgy.

Is this still an issue for anybody? If so do you have the same issue in a virtual terminal console? (i.e. vt[1-4]) Thanks in advance.

If i remember correctly, all keyboard inputs are spurious/delayed and they problem disappears only after reboot or after unloading and reloading the usb kerenel module.

I can confirm this, from memory.
When I had the problem, it was on all VTs.

But corrently I don't have the problem any more.
I am running Feisty.

As I understand it per amedee this has been resolved in Feisty. Is anybody else still having this issue?

I've had this keyboard bug on and off since I started with Ubuntu (which is about 4 days now). Machine is a P4 500MHz "spare" which I thought I'd try Linux on.
Symptoms are that on pressing a key I randomly get anywhere from one to hundreds of that key's characters. I can improve the situation by disabling keyboard repeats, but this does not help when logging in. The login often skips the password entry, so I assume the "Enter" key is giving extra entries too. I have tried a different keyboard - this appeared to work correctly at first, but later gave the same problem.
The problem ONLY appears on the GUI, if I ctl alt F1 to a terminal, the key entry is fine.
I'm using Ubuntu 6.06.1, and the CD and image check out. I'm updating the system (111 updates!) to see if that works, but I'm having to use my "other" PC to write this.
I'll gladly supply any other information that you may need, but I'll need instruction if it's anything other than very basic! (I've used computers for years, going back to MSDOS and before, but the UNIX stuff is all new to me ;-)

Hi John,

I had the same Problem with Ubuntu and Kubuntu Version 6.06 on my
Laptop.

In my opinion, the easiest way to fix that problem is to install the
Ubuntu 6.10 Edgy Eft Version.

There is no other solution at the moment to fix that issue in a
easy-to-use manner.

Best regards,

Frank

Updating to Ubuntu 6.10 (Edgy) works for me. But:

JohnP has upgrated to Ubuntu 6.10 but the issues still there. He works on a desktop system with SiS chipset.

I suggest to consolidate the requests refered to that kind of keyboard problems and give them more drive?

This bug report does not reflect my problem 100% but the status is "confirmed" (Importance: medium).

@Brian: I think that dealing with logfiles does not help us in that case because no errors will be throwed by any process. Have you got any idea how to trace the system (top, ps, lsof ...) ...

My bug report:
https://launchpad.net/distros/ubuntu/+bug/63147

console-setup just defines how the keycodes map to symbols (more or less); which keycodes get produced is up to the kernel. Reassigning.

Hi,

I can confirm the problem too ... my machine is a HP Comapq nx6125 with 7.04 (Final).
Outside X, on the console it works fine for me (resp. I haven't recognized this annoying bug there).

Cheers,
Benny

I have this problem running Feisty 7.04.

the probllllllllllllllllem is still present iiiiiiiiiiiiiiiiin feisty. Keyboard input iiiiiiiiiiiiiiiiis slow and random kkkkkkkkkkkkkkkkkeys are reopeated, Input on VTs is slowwwwwwwwwwwwwwwww too, but no spuuuuuuuuuuuuuuuurioussssssssssssssss reppppppppppppppppetitions tttttttttttttttthere................

Intel chipset, Pentium M, no USB keybbbbbbbbbbbbbbbboard.

This buuuuuuuuuuuuuuuug firrrrrrrrrrrrrrrrst surfaced aftttttttttttttttter installing the

2222222222222222.................6.20.16.28.1 Linux update. Never obbbbbbbbbbbbbbbbbserveeeeeeeeeeeeeeeeed before.

(This sucks!)

DDDDDDDDDDDDDDDDoes not go away wwwwwwwwwwwwwwwwwhen downgrading the keeeeeeeeeeeeeeeeernel. 2.6.20-15-generic haaaaaaaaaaaaaaaas thhhhhhhhhhhhhhhhe same bug.

Attached dmmmmmmmmmmmmmmmmmesg iiiiiiiiiiiiiiiiis from 2.6.20.16.28.1

A few new bits of information:

a) On VTs, keyboard works (i.e. no spurious repeats), but is slow.

b) Turning X keyboard repeat off kills the spurious repeats. Keyboard is still slow
and as is to be expected, keyboard repeat does not work (*g*)

c) Suspending and resuming the machine (this is a Thinkpad R40) makes the keyboard
fast & working as normal. I'm puzzled.

d) The phenomenon is persistant across reboots, not "random" in any way.

Removal of the i8kutils programme has fixed this problem for me.

I am assigning this bug to the 'ubuntu-kernel-team' per their bug policy. For future reference you can learn more about their bug policy at https://wiki.ubuntu.com/KernelTeamBugPolicies .

It also occurs at Ubuntu 7.10, kernel 2.6.22-14-generic on a desktop-PC with two different keyboards, but not from the beginning, Most of the times it occurs after about an hour of working with kile, since the las kernel-update ...

My problem with this "bug" was solved after the changing of the motherboard of my notebook. So I guess it's was a problem with the hardware (in my case, the USB ports).

Cheers,
Benny

Please have a look at bug #124406 and its duplicates which seem to describe one variant of this problem (spurious key repeats that stop by themselves). For several people, that bug was fixed after upgrading the kernel to Hardy Alpha2 (2.6.24-2-386).
Another key repeat bug (endlessly repeating keys, needs an X server reset) is discussed in bug #194214, with a patch available.

Since my last post, I updated the machine to (I think) 6.20. The problem seemed to be cured, but the machine itself died (motherboard failure) soon after, and since the problem was intermittent, I could not be certain of the cure.

I'm now running 7.20 as a dual boot machine (2 seperate hard drives) on my "main" PC with no problems, so I probably won't be able to make any useful contributions to this thread.

Cheers,

JohnP

Hi guys,

Just migrating this forward to the Hardy "linux" kernel package since Edgy and the 2.6.17 kernel has reached it's end of life for the 18 month support period. If and when you get a chance please confirm if this is still an issue with Hardy Heron 8.04. Thanks.

Ok, will do.
I booked the weekends of 21-22 and 28-29 june for reinstalling the pc that
has the issue. No time until then unfortunately.
I will report back either if it is still an issue or also if it's not an
issue any more.

I did a clean install with hardy heron 8.04, and I still have the same problem occasionally.

I think that this bug is related to https://bugs.launchpad.net/ubuntu/+source/bluez-utils/+bug/32415 because it only happens on the bluetooth keyboard. My ps2 keyboard doesn't have this problem.

Anyway I'm going to unsubscribe from this bug, because I am switching from Ubuntu to Opensuse, which has better out of the box support for bluetooth.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Unfortunately this bug report is being closed because we received no response to the last inquiry for information. However, the Intrepid Ibex 8.10 Beta release was most recently announced - http://www.ubuntu.com/testing/intrepid/beta . If you are able to confirm this is still an issue with this most recent release please feel free to reopen this report. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks.
