How to get Kernel backtrace

How to get Kernel backtrace Since kernel version 3.7 with the new modeset code we have a lot more self-checks in the code. If one of these checks fail it'll result in a backtrace in dmesg. The good thing is that even really small issues in the code can be caught much earlier (often before it negatively affects the end user experience), the downside is that we'll hit many more call trace issues...
