Hi, Luxmark (both 2.0/2.1) works fine on my IVB machine. The back trace you provided below doesn't indicate it's a beignet related problem. It hadn't enter beignet domain and just crashed in luxmark internal.

Beignet lacks of some llvm intrinsics support such as llvm.uadd.with.overflow.i32(). Will fix it next week.
