dmesg of running system
Hardware: Retina MacBook Pro 13", Intel Core i5 4258U with Intel Iris 5100
integrated graphics.
Distribution: Ubuntu 15.04 daily release
Kernel version: 3.19.0-13-generic
Output from glxgears -info:
GL_RENDERER = Mesa DRI Intel(R) Haswell
GL_VERSION = 3.0 Mesa 10.5.2
GL_VENDOR = Intel Open Source Technology Center
This bug affects all distributions using kernels after 3.14.
On my hardware, 1 core of 4 is stuck at about 70% load, even without any
CPU-intensive operation running.
If the system is booted without loading i915 module the CPU load stays at
normal levels.</pre>
