4.15.4-300.fc27.x86_64

How reproducible:
N/A

Steps to Reproduce:
1. N/A

Actual results:
Messages as above.

Expected results:
Shouldn't get messages as above.

Additional info:
Maybe https://bugs.freedesktop.org/show_bug.cgi?id=103206?  Second last comment there says:

Resolved in drm-tip, please test with that.

Can we get a kernel with that in it please?
Comment 1 Laura Abbott 2018-03-06 20:38:28 UTC 
If you point me to which commit fixes it I can add it to Fedora.
Comment 2 Brian J. Murrell 2018-03-06 20:41:15 UTC 
I'm afraid I only have as much as https://bugs.freedesktop.org/show_bug.cgi?id=103206 says.
Comment 3 Brian J. Murrell 2018-03-08 20:24:13 UTC 
Any further ideas on this?  I am getting a new abrt every few seconds with this.  I currently have 858 xorg-x11-drv-intel "crashes" in abrt.

Can you not just pick up the drm-tip as the upstream bug report advises?

Same issue here on kernel 4.15.6-200.fc26.x86_64
