Created attachment 108702 [details] kern.log To reproduce the error I start Chrome (Version 38.0.2125.111 (64-bit)) and start the Tweetdeck App I have installed. Whenever I click the "New Tweet" button, the system freezes for about a second and then the screen blacks out. While the rest of the system is still running, there is no way re-enabling ANY graphics output from the Intel graphics adapter. I can only ssh into the machine and do a controlled reboot to regain any output. I have attached the kern.log as instructed by the log entry. The /sys/class/drm/card0/error file only contains the following line: no error state collected Any clues for me? Adam
