Dell Vostro 1510: need to use these kernel parameters: i8042.reset, i8042.nomux and i8042.noloop
Last modified: 2009-12-18 04:01:18 EST
Description of problem:
In order to use keyboard and mousepad properly in Dell Vostro 1510 notebook, it must make use of i8042.reset, i8042.nomux and i8042.noloop parameters at the boot time.
First the keyboard and mousepad works sometimes, but suddenly they stop work, then, using i8042.reset resolve this problem.
But, when few windows are opened (using compiz), the X responds only when the mousepad or keyboard are touched. Then, the use of i8042.nomux and i8042.noloop resolve this problem.
Even with this parameters, I have experienced that the keyboard and mousepad stop work suddenly, but I've noted that the system still running well.
Version-Release number of selected component (if applicable):
In Dell Vostro 1510, try to use fedora without the parameters above, than try to use one by one.
Steps to Reproduce:
1. Install Fedora with at least i8042.reset to proceed
2. After installed, boot fedora with just the standard parameters
3. When keyboard and mousepad doesn't respond, use the i8042.reset parameters
4. with i8042.reset parameters, try to open some windows with compiz enabled, then you may have some trouble with keyboard, X will respond only by receiving some activity of mousepad or keyboard
5. then, use the others parameters
Must use i8042.reset, i8042.nomux and i8042.noloop to work properly with Dell Vostro 1510
No need to use any kernel parameters
Ubuntu 8.10 have the same trouble
Is just using nomux alone enough? Upstream linux 2.6.29 only has nomux enabled for the 1510.
Added the vostro 1510 to the nomux quirk list in 22.214.171.124-170.2.54

Well, I'm using just nomux now, and it seems to be ok.
After using just nomux I've experienced my first sudden freeze.
The system was running normally but the mouse cursor freeze in the hand stage (cursor at link). I could move the cursor but not click. The keyboard had no response too, except for some of the Fn functions, like the screen brightness, battery information (Fn+F3) and Hibernate (Fn+F1).
Then I pressed the Power button and wait for the 40 seconds to shutdown the system.
Do I have to use another kernel parameter to avoid this hang?
kernel-126.96.36.199-170.2.56.fc10 has been submitted as an update for Fedora 10.
kernel-188.8.131.52-170.2.56.fc10 has been pushed to the Fedora 10 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update kernel'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F10/FEDORA-2009-3008
kernel-184.108.40.206-170.2.56.fc10 has been pushed to the Fedora 10 stable repository. If problems still persist, please make note of it in this bug report.
I'm testing this new kernel
Thank you very much.
So I'm using this new kernel version (220.127.116.11-170.2.56.fc10.x86_64) and I'm not using the nomux kernel parameter.
But, the keyboard and touchpad still stop responding after some time.
The system does not stop working, because when it's crashes I was burning a DVD, and it finish the jobs after the crash and when the keyboard and touchpad stop responding, I've tried to shutdown the computer pressing the power button, but a balloon appears saying that the system will not shutdown because it was burning a DVD.
So, it seems that this bug was not resolved yet.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
