On shutdown/restart, after showing the exit-plymouth animation, it goes to text mode, and outputs some info, a stack trace, and stating that it in fact is a bug. I am not sure how to get the log, because i searched through everything in /var/log and found nothing like the text that was output. After showing the information, everything locks up, and the computer does not shut down/restart. Attached a picture of the screen to show how it looks when it has printed the oops message. Sorry for the poor quality.
If you give me a hint on how to retrieve the log, I can append it to the bug report.
I think it must be a driver issue, because it started happening after buying new motherboard, cpu:
