My laptop has Intel B960 (2.2GHz x 2) with 4 GB RAM. OS is Ubuntu 12.04 with all updates to current date.
I am getting a peculiar issue since about 2 weeks - when I browse a HTML5/CSS3 website in Chrome, sometimes (randomly) the system freezes - mouse, keyboard nothing seems to work. Ctrl-Alt-Del wouldn't work. The mouse pointer moves but clicking doesn't do anything. There is no such issue in Firefox. Only Chrome on Ubuntu has the problem.
