Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Do you know if this issue happened in a previous version of Ubuntu, or is this a new issue?

[Le Gluon Du Net (legluondunet)]

I directly installed raring on a macbook air 2.1. I tried a lot of soluce on internet, none of them solved this bug.

[Le Gluon Du Net (legluondunet)]

Ther last kernel stream does not work with my macbook air.

[Le Gluon Du Net (legluondunet)]

in fact I can not test last upstream kernel because my keyboard is inactive with it.

[Joseph Salisbury (jsalisbury)]

Can you also test some previous kernels, so we know if this is a regression or not:

v3.3 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-precise/
v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/
v3.5-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc4-quantal/

[Le Gluon Du Net (legluondunet)]

Hello, sorry to take your time for a problem that was not Linux/Ubuntu related. In fact my soundcard was dead. You can close this bug.

Regards.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

Finally resolved in kernel 3.13, look here:
