--- Comment #8 from dog <paul.a.parenteau at intel.com> ---
Intel OTC graphics driver QA performed tests using eDP+HDMI on 3 different SKL
platforms… (a production one, SKL-y and SKL-H)

In all three configurations, the bug was not reproducible using latest kernel
and graphics stack (The platform never hung)

Next QA test is to connect two displays on the platform (+eDP that makes 3
pipes), unfortunately the platforms QA has available have only 2 pipes
available , eDP+HDMI. Testing will be done later ths week on a non-production
platform with 3 pipes in order to test this as described in the bug.

Note that the bug report is focused on Fedora 22, a distro that is a year old.
