Vinícius Milanez Couto, in order to allow additional upstream mainline kernel 
developers to examine the issue, at your earliest convenience, could you please 
test the latest mainline kernel? Please keep in mind the following:
1) The one to test is in a folder at the very top of the page (not the daily 
folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was 
released upstream.
4) Install instructions are available at 
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't 
boot into the OS) please make a comment in your report about this, and continue 
to test the next most recent kernel version until you can test to the issue. 
Once you've tested the mainline kernel, please comment on which kernel version 
specifically you tested. If this issue is not reproducible in the mainline 
kernel, please add the following tags by clicking on the yellow circle with a 
black pencil icon, next to the word Tags, located at the bottom of the Bug 
Description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the issue is reproducible with the mainline kernel, please add the following 
tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

It is most helpful that after testing of the latest mainline kernel is
complete, you mark this report Status Confirmed.

Lastly, to keep this issue relevant to upstream, please continue to test
the latest mainline kernel as it becomes available.

Thank you for your help.
