It seems that you have a Haswell CPU and I think you are having the same problem with me (You can find a thread on the mailing list a few weeks ago about it). The support for Haswell CPU is not finished yet and it will very likely hang the GPU.
>>>>> Are you using beignet 0.8 release? Beignet v0.8 have not supported HSW, you should use Beignet git master, the Haswell support almost has finished in master. Pay attention that you should apply a kernel patch in attachment if you want to run kernels with local memory. This is because of drm's restriction, and will drm guys is handing it.
If still any problem, welcome to report.
P.S. I don't think the system is frozen. It might appear that way because the display is not updating. However, if you wait long enough and/or try to kill the running process with Ctrl-C, you can still get you system back.
>>>>>>System frozen may be caused by GPU hang and your system doesn't enable hang check. Try echo -n 1 > /sys/module/i915/parameters/enable_hangcheck with root user.
