Public bug reported:
Since Intrepid, volume keys of Zepto Znote 6625WD don't work correctly as already mentioned here (also in 32bit):
However, a fix for the 6615WD has been already released (look for Zepto):
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:
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:
For each model the DMI signature hast to be added and maybe a specific fixup method has to be implemented.
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.
The testing results can be found here (german):
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? :)
