[STAGING] Kernel regression

Since about a week I get multiple notifications about a serious Kernel problem being detected. Trying to report the bug through apport fails, since it just crashes at some point. I filed a separate bug on that.
I have no idea what the crash is about, there is seemingly no correspondence to my usage and the problem. Also, I do not see any effect or performance impact.
