Hi, blind Pete.

Thank you for taking your time to answer.

Yes, I tried different kernels focusing con Ubuntu distro. I don't remember the exact kernel version, but at least those included by default in the Ubuntu 12.04 lts and 14.04 lts ISO image, which worked for me. The latest Ubuntu version I tested was the nightly 15.04 from the 7th of January.
