I tried to reproduce with the following configuration without success: -Software: kernel version : 4.11.3 architecture : x86_64 kernel driver : i915 bios revision : 5.6 bios release date : 09/29/2016 mesa : 17.0.5 -Hardware: platform : SKL Canyon, NUC6i7KYB cpu information : Intel(R) Core(TM) i7-6770HQ CPU @ 2.60GHz gpu card : Intel Corporation Iris Pro Graphics 580 (rev 09) displays connected : DP-3 -Firmware: dmc fw loaded : yes dmc version : 1.26 guc fw loaded : NONE guc version wanted : 6.1 guc version found : 0.0 Also tried with latest 4.11.10 and neither manage to reproduce. Could you please try with 4.11.10 or 4.12 and if the problem persist send full dmesg with parameter drm.debug=0xe on grub boot options? Jrnlctl could also be helpful. Thanks. > Could you please try with 4.11.10 or 4.12 and if the problem persist send

Will do when they appear: today I noticed that only 4.11.9-200.fc25 is available.

journalctl kernel 4.11.12
According https://bugzilla.redhat.com/show_bug.cgi?id=1463085 and https://bugzilla.kernel.org/show_bug.cgi?id=196233 it seems this problem is reported only on Asus laptop UX305UA, UX305U and UX306U In my case I have UX305UA and I did not have any problem with kernel 4.11.4 and previous. The problem has been introduced by kernel 4.11.5 and following. I am affirmative about that. I attach journalctl of failing boot with kernel 4.11.12 with parameter drm.debug=0xe on grub boot options. Message "[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 31: Can't calculate constants, dotclock = 0!" is present since 4.11.5 Assuming this is the same as https://bugzilla.kernel.org/show_bug.cgi?id=196233. Judging by the git logs, the only thing that looks potentially suspicious between v4.11.4 and v4.11.5 in drm/i915 is commit 6b183d1b84764e81dcb64f6b41151e79db23679c Author: Jani Nikula <jani.nikula@intel.com> Date: Fri Mar 10 15:27:58 2017 +0200 drm/i915/vbt: split out defaults that are set when there is no VBT commit bb1d132935c2f87cd261eb559759fe49d5e5dc43 upstream. Please try reverting that. Another thing to check, are you booting in legacy BIOS or UEFI mode?

Quoting https://bugzilla.kernel.org/show_bug.cgi?id=196233#c15 "i just built the 4.13.0-rc3 kernel WITHOUT bb1d132935c2f87cd261eb559759fe49d5e5dc43 and that's working for me. To verify i built the same kernel WITH bb1d132935c2f87cd261eb559759fe49d5e5dc43 and got the same error as before." Confirms the culprit.

Created attachment 133428 [details] [review] drm/i915/vbt: ignore extraneous child devices for a port Please try the attached patch, obviously don't revert bb1d132935c2 ("drm/i915/vbt: split out defaults that are set when there is no VBT") for this. And please attach dmesg with drm.debug=14 regardless of the outcome. Created attachment 133429 [details]

I tested the latest kernel with your patch. It worked. The dmesg is attached. Thank you very much.
