At one time after a successful login, opening Chrome Browser, which is usually really fast to open, took more than 10 minutes to open. After that I tried to even login and the system never left from the login screen. I decided to hard-reset my computer and booted instead with the previous available Kernel version. (Version 4,4,0-91) and everything works fine. In summary: Linux Kernel 4.4.0-91-generic and everything before it works fine. Linux Kernel 4.4.0-92-generic makes my computer unusable.
