Daniele -- other Linux distributions may or may not have this problem. Also, they may have other problems that are not present in Ubuntu. It is all a matter of trial and error and publicizing the results. However, what we do know at this point is that the removal of samsung-laptop kernel module in UEFI mode (Colin King's patch) likely fixes the bug. If you are intent to try other Linux distributions, I suggest that you disable FastBios and set "OS Mode Selection" to CSM OS, boot from the installation disk and execute "lsmod | grep -i samsung". If you see samsung_laptop in the output, do NOT try booting Linux in UEFI mode.
If you want to try installing Ubuntu, get a latest daily build from http://cdimage.ubuntu.com/precise/daily-live/current/. Installing from the latest builds in UEFI mode should be safe. See Denise's comments in post #120.
