[Beignet] [drm] stuck on render ring

[Ernst Lenzer]

I'm trying to use pyrit with OpenCL extension with an Intel 4600 using Beignet. I'm running Debian Jessie, Kernel 3.16, pyrit 0.8.1-1 from the official Debian repositories and ran "echo 0 > /sys/module/i915/parameters/enable_cmd_parser" to avoid the known bug with kernel 3.16. "pyrit selftest" produces the following error in the terminal:

>>>>>>>>>>>>>>>>
Exception in thread OpenCL-Device 'Intel(R) HD Graphics Haswell M':

The following shows up in dmesg:

Without Beignet pyrit works fine.
