["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Gioele Barabucci, could you please test the latest mainline kernel (not
the daily) via http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.12-rc6-saucy/ and advise to the results?

As well, because Samsung does not easily reveal what the latest BIOS is for this model, could you please download the latest firmware software as per http://www.samsung.com/uk/support/model/NP900X3D-A03IT-downloads, and advise if a BIOS update is available? If so, when you update to this, does it change anything?  If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Thank you for your understanding.
