I'm using an HP 8470p notebook and a HP docking station. Attached to this docking station is a DELL 2713HM monitor (max. resolution 2560x1440) through display port. KMS is working fine, i can see the Fedora 20 bootlogo and the GDM is working correctly. But as soon as the GNOME shell starts the kernel throws a WARNING, complains about FDI train failed and the screen goes black.

Can you please boot your system with drm.debug=0xe, reproduce the issue and then attach the complete dmesg? Please make sure that dmesg contains everything since boot-up, extend the log buffer with log_buf_len=4M if needed.

I've checked-out the latest drm-intel-nightly git and applied your attached patch. Unfortunately this doesn't help. It's still the same issue. Entering GNOME 3 throws listed kernel warning and blanks my big screen.

Wonderful, its working. I've used the latest git and *only* your second patch (the first one makes it bad again). The kernel warning is gone and the big screen always shows an image. Thanks :) There is another warning message when removing the laptop of the docking station. But that's for another bug report.

Created attachment 88220 [details] [review] updated patch patch v2 was ripped apart in review, so this one here tries yet another approach. At least conceptually this should be sound. Please test.
The latest patch is not working for me, the display stays blank. I guess you need another dmesg log output?
Created attachment 88279 [details] dmesg output with drm.debug=0xe on latest drm-intel-nightly + patch #4
Created attachment 88282 [details] [review] next patch version Ok, this is getting a bit embarassing ;-) Previous patch was indeed rather bogus for your issue, but I've stared at the update dmesg some more and I think patch v2 was indeed the right thing. Now updated to address the issues pointed out in the review. Please test.
Works again :)
