Display Port error with kernels > 3.15.5-2

Thorleif · 2014-07-30 08:46:23

Hi folks !

Yesterday I have updated my kernel to the version 3.15.7-1. As yesterday I didn't perform any reboot, I didn't experience any issue.
This morning when I have booted my machine, I have first got the following errors: "[drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting".
And, since, I only can get my secondary display by frenetically switch off and switch on until it works.

My setup is a Latitude E7440 docked on an E-port and all the device are plugged on the dock. The secondary display is connected to the dock using the DVI port (but it seems to be wired to the DP1 cf. xrandr).

Is there any fix ? Is there any non too intrusive manner to fix it properly (it is my working station so I don't want to break it more) ?

Cheers,

Edit: For now, in order to get the good behaviors, I have downgraded the kernel version.

FYI ...

It's still the same with the 3.15.8-1.
