Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1391953/+editstatus and add the package name in the text box next to the word Package.

Set package to "linux" for kernel component

[Breno Leitão (breno-leitao)]

Tim,

Should we also track this for 14.04.2, or, tracking for uTopic is enough to track the inclusion on 14.04.2 (since 14.04.2 will use the same utopic's kernel) ?

Thank you,
Breno

@berno-leitao

If this gets into utopic's 3.16 kernel it will automatically be part of the 3.16 kernel for Trusty.
If this needs to also be in 3.13 let me know.

Hi Chris,

>If this gets into utopic's 3.16 kernel it will automatically be part of the 3.16 kernel for Trusty.
Great. That is what I need.

>If this needs to also be in 3.13 let me know.
Ok. no need to have it on 3.13 tree.

[Brad Figg (brad-figg)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-utopic' to 'verification-done-utopic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Breno Leitão (breno-leitao)]

I was able to test this kernel (3.16.0-26-generic) on my machine, and also checked for all the commits and it seems fine. Marking it as validated.
