Hi Krisman, i've tried with the option intel_iommu=igfx_off in the grub as you
mentioned, but this i think is not a real failure because for the following
reason :


gem_workarounds:1418) CRITICAL: Test assertion failure function
check_workarounds, file gem_workarounds.c:103:
(gem_workarounds:1418) CRITICAL: Failed assertion: workaround_fail_count() == 0
(gem_workarounds:1418) CRITICAL: Last errno: 2, No such file or directory
(gem_workarounds:1418) CRITICAL: error: 5 != 0


the test is trying to access to a file but there is not in igt folder.
