Comment 4 for bug 1491657

Cristian Aravena Romero, this is not a bug. In the future, instead of making bug reports about log entries you may not be familiar with, please first review the respective man page (man dmesg). If this doesn't provide the desired clarity, one may want to engage:
* The Ubuntu Support Tracker - https://answers.launchpad.net/ubuntu/+source/linux/+addquestion
* The appropriate mailing list - http://www.ubuntu.com/support/community/mailinglists
* The Ubuntu forums - http://ubuntuforums.org/
* or one of the Ubuntu IRC channels - https://wiki.ubuntu.com/IRC/ChannelList

Thank you for your understanding.
