dmesg from 20170717 drm-tip

i915 fails to perform link training on resume with a Chamelium attached to the
DP connector. This is triggered by launching one of the DP suspend/resume IGT
chamelium tests such as dp-hpd-after-suspend or dp-edid-change-during-suspend.

The error appears to be: dp_aux_ch timeout status 0x7d4003ff (full dmesg from
today's drm-tip is attached).

Information about the setup:
* Kernel: drm-tip 0ea81ff8a340aa1f2bc863f4c8e631542e47c98e
* Distro: Arch Linux (NOT using the distro's kernel)
* CPU: i5-6600K

Ironically, it makes the IGT test pass because a hotplug uevent is generated
because of link training failure.</pre>
