Fatal trap 12

Since upgrading my Lenovo T450 from r333740 to r334167 I'm experiencing 
several "Fatal traps 12". Before the update i did not have any of those.  
In all cases the traps occured some time after resume.

Below there is some output found in /var/crash/core.txt

If there is any other information i can provide for solving this, please 
let me know.
