Description matthias.a.lee 2015-03-29 18:43:44 UTC

to reproduce:
- start ubuntu 15.04 and log in
- use CTRL+AL+F2 to switch to TTY2. (or a different TTY)
- Watch the screen glitch: http://youtu.be/MqPi5dURZ8s
- sometimes it's so bad it will not recover and the computer needs to be forcefully rebooted.

I should note this is on the newest generation Thinkpad X1 Carbon (Gen 3)
I have had experienced this crash with Kernel 3.17, 3.19 and 4.0RC5

Also filed this bug with ubuntu: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1436590

Comment 1 matthias.a.lee 2015-03-29 18:48:23 UTC

I suspect this bug affects all of the current thinkpads, at least the ones with haswell processors, but i have not been able to verify this.
