    GPU of NUC Skull 6iKYK is blacklisted in Chrome


      I have NUC Skull 6iKYK and Ubuntu 14.04 OS with latest kernel installed (32GB RAM included).


      We use a program that presents panoromic images in the Google Chrome.


      I installed the same program to NUC Skull and when I run the the program

      Chrome actually loads the images (we verified) but it is apparently not able to render them.

      It seems that WebGL is detected but does not work properly.


      Then, we found that GPU of NUC Skull 6iKYK is blacklisted in Chrome.


      Chrome needs to be restarted.

      We do see the following errors in dmesg:


      [ 4.604922] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* failed to enable link training

      [ 4.613509] [drm:intel_dp_start_link_train [i915_bpo]] *ERROR* failed to start channel equalization

      [ 4.729164] [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU pipe A FIFO underrun


      Has anyone ever recognized that problem ?

      Thank you in advance for any help you support.
