--- Comment #10 from misc-freebsd-bugzilla at talk2dom.com ---
Same issue here (drm_intel_bo_set_softpin_offset SEGV).

FreeBSD 11.0-RELEASE-p10
i7-4790K "Devil's Canyon" (Haswell) with HD 4600 (GT2)

libdrm-2.4.80_1,1
llvm39-3.9.1_1
beignet-1.3.1_1
ocl-icd-2.2.11_1

Initially failed with beignet (openCL 2.0)
Also fails with beignet (openCL 2.0) + attachment 180620
Also fails with beignet (openCL 1.2) + attachment 180620

Typical failure (always running as root):

"clpeak" crashes in the same way, with similar backtrace.

Volunteering to test.
I would appreciate config option for beignet to toggle openCL 2.0 support!
