Description of problem:
After kernel loading thousands of error messages (view log file)
A few seconds after the login appears the screen start to flicker and is unusable for login, but if the touchpad is used the screen becomes stable and remains readable until the touchpad is used. After login same problem. Changing screen resolution from 1920x1080 to 1600x900 and the screen becomes and stays usable. Just changing the frequency from 60hz to 59 same flickering and sync errors with 10920x1080. So login with touching the pad works, after login the resolution changes to 1600x900 and the desktop is usable.
I tried some kernel parameters with similar screen problems but no effect.
I tried newer kernel problem persists.

Fedora 25 & Rawhide (26)

How reproducible:
Every bootup

Steps to Reproduce:
1. Power  on

Actual results:
Multple PCI error messages
Flicker and sync errors

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 25 kernel bugs.

Fedora 25 has now been rebased to 4.10.9-200.fc25.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26.

If you experience different issues, please open a new bug report for those.
