After testing and research from our QA team, it was found that the specific config file from FI that was being used to compile the kernel, had a lot of disable parameters to improve performance while running IGT. The problem was that some of those parameters were required to use the firmware effectively. It was agreed to use a generic config file from kernel.org. This test are now passed with the attached kernel and the last configuration known:

This test still are failing but with a different issue, they will be tested again and if needed a new bug will be open. Thanks.
