id this issue occur in a previous version of Ubuntu, or is this a new issue?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

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 happen to know if this bug always existed in Trusty? Has it also happened in prior releases?

No idea, I got this laptop this weekend.

Joseph Salisbury (jsalisbury) wrote :

I'd like to perform a reverse bisect to figure out which commit upstream fixes this regression. It would be very helpful to know the last kernel that had this issue and the first kernel that did not.

Can you test the following kernels and report back? We are looking for the earliest kernel version that doesn't have this bug:

v3.13-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc3-trusty

If v3.13-rc3 exhibits the bug then test v3.13-rc6:
v3.13-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty

If v3.13-rc3 does not exhibit the bug then test v3.13-rc2:
v3.13-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc2-trusty

You don't have to test every kernel, just up until the first kernel that does not have this bug.

Thanks in advance!

Sorry, the links should all point to the 3.14 release candidates and not 3.13.

v3.14-rc4 doesn't have the problem.

I started a "Reverse" bisect between v3.13 final and v3.14-rc1.

The first test kernel is built up to commit:

Can you test this kernel and post back if it has the bug or not? I'll build the next test kernel based on your result.

I re-uploaded the test kernel, and it should now be available at:

This kernel (linux-image-3.13.0-031300rc3-generic_3.13.0-031300rc3.201404091235_amd64.deb) has the bug.

Joseph Salisbury (jsalisbury) wrote :

Sorry for the delay, Jonathan. I'm having some issues building kernels during the bisect due to another bug that happens while building. I'll investigate that further and should have another test kernel shortly.

Can you see if this bug still exists in the latest upstream 3.13 kernel, which can be downloaded from:

I believe this bug will be fixed by commit 15d75fcebdf78d316a980487eddcac8e4f1574c8, which is in Trusty as of Ubuntu-3.13.0-28.51. This commit is a cherry pick of upstream 54290fa6.

Can you test the 3.13.0-28.51 kernel and confirm if it fixes this bug or not? It can be downloaded from:

OK, the above kernel works, but kern.log still complains about a "atkbd: Unknown key released (translated set 2, code 0xf8 on isa0060/serio0)".

(For other testers, you also need to download linux-image-extra-3.13.0-28-generic_3.13.0-28.51_amd64.deb).

What's the current status of this bug? I have the Folio 1040 and can't turn on wireless.
