Comment 2 for bug 790995

Cristian Aravena,thank you for reporting this and helping make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:
apport-collect 790995
As well, as per upstream, the next step is to test against newest kernel and, if reproducible, post the results to <email address hidden> for analysis. Could you please do so via https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds and report back the results?
