kernel log

The system randomly freezes and doesn't react to anything afterwards. Not even
the magic keys can reboot the system.

Processor model is Intel Core-i7 5500U with the integrated GPU.
Kernel version is 4.0.0-rc1, which is required to even get X / gdm working with
the system.

I've attached the kernel log messages which shows an instance of this problem.
Please request any information needed and I'll happily provide it.
