<pre>Hardware: laptop with Intel Core i5 6200U CPU
Software: Fedora 24 64 + all updates + kernel 4.8.6
Whenever I run any OpenCL applications my entire desktop almost completely
freezes: the mouse cursor barely moves, I cannot type anything, there's a huge
delay whenever I try to interact with anything. In short the desktop becomes
unusable.
This happens for instance when running:
$ clpeak --all-tests
for most tests CPU usage remains negligible.
I have verified the issue with both Intel proprietary OpenCL drivers ( Intel
intel-opencl-r3.0 (SRB3) Linux driver package ) and Beignet open source
drivers.</pre>
