Ubuntu 16.04 freezes at random



I am running a fresh install of Ubuntu 16.04 on my Toshiba Satellite L50. Fairly often (once per hour or so) it randomly freezes. The system is installed in UEFI mode, although it had the same problem during a test install in Legacy. The previous install of Linux Mint 17.2 worked with no problems.




I've tried the following:




  • Updating kernel to 4.6.2

  • Installing Nvidia prime

  • Trying to enter shell by pressing ctrl + alt +f3 (alternatively ctrl + alt+ f1)



I've been searching for a solution for a long time now, with no result. Can somebody help?




This a copy of syslog, the freeze happened aproximately at 22:00



I will answer my own question, maybe it will help somebody in the future. After many trial and error, it seems that disabling VT-x option in UEFI options seem to solved the freezing.



So far running a few days without problems.
