[Bug 1318040] Re: bbswitch prevents suspend and taints kernel
Still facing the issue with kernel 4.2.0-23-generic, gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2), bbswitch-dkms 0.7-2ubuntu1, no bumblebee package installed.

Do you have a full dmesg since the first boot?

This problem may occur when your compiler (gcc) is different than the one used to compile the kernel. Have you installed an older gcc version (maybe via CUDA?).
