--- Comment #4 from Stanislav Lisovskiy <stanislav.lisovskiy at intel.com> ---
The test triggers link failure with Chamelium and then expects a hotplug event. 
However because HOTPLUG event timeout sometimes seems to be way to short, we
get a link failure hotplug event however only after test case fails:

<6> [839.991645] [IGT] kms_chamelium: exiting, ret=98
<7> [840.532587] [drm:gen8_de_irq_handler [i915]] hotplug event received, stat

So now there we have even more reasons for this patch to land:
