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.

That is why it shows -ENOENT here. My understanding is it is not related to this issue. So, my understanding is that you ran with that parameter and it still fails, can you please provide the entire log for confirmation? Thanks! Humberto bug need your attention Can you try with:

Hi Krisman, is the same failure with the patch applied Still no changes with kernel: commit ad6ab9f96437f0cb1f4d8a7840fd9eeb894eb12e Author: Gustavo Padovan <gustavo.padovan@collabora.com> AuthorDate: Fri Aug 18 15:26:42 2017 -0300 Commit: Gustavo Padovan <gustavo.padovan@collabora.com> CommitDate: Fri Aug 18 15:26:42 2017 -0300 drm-tip: 2017y-08m-18d-18h-21m-46s UTC integration manifest No patches applied.
