            Bug ID: 96564
           Summary: [BSW] igt / gem_exec_parallel / * contexts subcases
                    send segmentation fault

Dmesg

The following sub cases are failing sending segmentation fault:

igt at gem_exec_parallel@contexts
igt at gem_exec_parallel@bsd-contexts
igt at gem_exec_parallel@blt-contexts
igt at gem_exec_parallel@vebox-contexts


Those test cases are failing sending out a segmentation fault.

The problem seems to be how are the test managing the ioctl-wrappers.
