<pre>==Regression==
--------------------------
Regression: No. Firstly tests OpenCL on BSW.
Ubuntu: 14.04
==kernel==
--------------------------
drm-intel-next-queued: git-65de79
==Test cases==
Beignet: git://anongit.freedesktop.org/git/beignet (master git-6aae2e8)
failed cases: compiler_async_copy_char2
compiler_async_copy_uchar2
==Bug detailed description==
-----------------------------
Disable RC6 in kernel makes some OpenCL test cases fail. If enable RC6(no
i915.enable_rc6=0 in grub), the case works OK.
e.g. run compiler_async_copy_char2()
compiler_async_copy_char2() [FAILED]
Error: dst[i] == src[i]
at file /home/OpenCL/beignet/utests/compiler_async_copy.cpp, function
compiler_async_copy_char2, line 46
==Reproduce steps==
----------------------------
1. set "i915.enable_rc6=0"
2. utests/utest_run -c compiler_async_copy_char2</pre>
