Problematic volume control keys and mute key of several notebooks + Patch

Bug Description

Since Intrepid, volume keys of Zepto Znote 6625WD don't work correctly as already mentioned here (also in 32bit):
https://bugs.launchpad.net/ubuntu/+bug/278103

However, a fix for the 6615WD has been already released (look for Zepto):
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.27.8

I figured out that this fix would also fix the 6625WD's problem so the kernel just needs apply the fix for this model.
I attached a diff to widen the DMI signature to target the 6625WD, too (tested with mine, works fine).

There are users of the 6615WD model who still have this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/261721/comments/20

Seems like Zepto changed DMI entries in newer models of the 6615WD.
I obtained the dmidecode output of such a user and widened the DMI signature to target those models also (tested by a user, works fine).

Users with a Fujitsu Amilo Xi 2428 are also affected by this bug but the mute key is also broken.
I added a new method for fixing this notebook and added the DMI signature as well (tested by a user, works fine).

There seem to be more Notebooks with this bug:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/291612/comments/8
- Toshiba Satellite Pro U300
- Toshiba Satellite U305
For each model the DMI signature hast to be added and maybe a specific fixup method has to be implemented.
If those users post their output of "dmidecode" and "showkey -s" (virtual terminal) for each problematic key, I can try to add their models to the patch, too.

However, both 6615WD models and the 6625WD need the same already implemented fixup method so I just linked the DMI signatures to that method.
Probably this patch needs to be applied to the Jaunty kernel as well.

Some testing results can be found here (german):
http://forum.ubuntuusers.de/topic/intrepid-multimediatasten-laustaerke/

This is my first kernel hack and my first bug report ever, so I wonder if I should file a bug report to kernel.org myself or will you guys do the job for me? :)

SRU Justification

Impact: volume and brightness keys auto-repeat forever rendering brightness and volume controls mostly usless

Fix Description: add quirks for these laptops to prevent them repeating

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-jaunty.git;a=commit;h=baad507a2aca0f997f01f964e03f79c4ec622cf4

Risks: this is a model specific quirk and has been tested by a number of affected users

TEST CASE: see bug

Works fine on my 6615WD.
The bug wasn't fixed for me in 2.6.27-11.

Works for me @ my Znote 6625WD

Thank u very much :D

P.S. Installed your .deb packages from http://forum.ubuntuusers.de/topic/intrepid-multimediatasten-laustaerke/

@Marius -- that patch looks like it does the right thing. If you could sign it off for me, that is supply a Signed-off-by: Marius Wenderoth <email> to me. See Documentation/SubmittingPatches (search for Developer's Certificate) for details of what this is and means. Once I have that I can work on getting it into our kernel and push it upstream.

@All -- I have applied Marius' patch to the latest intrepid kernel. If you could test those and report back here. This will help support any SRU to Intrepid. The kernels are at the URL below:

http://people.ubuntu.com/~apw/lp330259-intrepid/

I have also build some Jaunty kernels with the same patch. If you could test those, even on an Intrepid userspace that would also be helpful. We will need to justify those via SRU for Jaunty as well. These kernels are at the URL below:

http://people.ubuntu.com/~apw/lp330259-jaunty/

Done so.

Your intrepid kernel seems to work fine.
Wasn't able to install the jaunty kernel:
Headers: "Dependency is not satisfiable: libc6"
Image: "Dependency is not satisfiable: wireless-crda"

This bug was fixed in the package linux - 2.6.28-11.35

Are you running Ubuntu 8.10 (Intrepid) or 9.04 (Jaunty) ?

I'm running 9.04 Jaunty, with 8.04 and 8.10 I have problems with sound keys, now I have the same problem and when I close my laptop happends the same like when I press volume keys.

Accepted linux into intrepid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I have the same problem with my laptop, a Gericom Hollywood Advanced 32100

this is my sudo dmidecode: http://paste.ubuntuusers.de/395666/

and my sudo showkey shows me
louder (Fn+F5): keycode 115 press
less loud (Fn+F6): keycode 114 press
when I press the buttons

I'm experiencing the same problem with my Lenovo 3000 V100. I experienced the problem in the past but it mysteriously disappeared and it just now reappeared. Here are my dmi and showkey logs:

I'm in the same situation as #12 on my Zepto Znote 6025WD.
The problem just appeared.
When I run sudo showkey it says:

key.. 114 press
key.. 115 press

No release.

I am having this problem on 9.10 and 10.04 lts.
I use a Mivvy G310 netbook, it has a N450 processor.
I have this problem with the volume keys.
Will this be fixed or do I need to open another bug?
