Created attachment 108702 [details]
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?
