Description BZ 2018-07-04 10:38:11 UTC 
Description of problem:

When attempting to log out if an interactive session, the screen blanks and a series of errors appears over the course of about six minutes. Finally a login screen appears, but the keyboard and mouse are not responsive and it's been necessary to power-cycle the system.

Version-Release number of selected component (if applicable):

Fedora 28 Xfce Spin
Kernel 4.17.3-200.fc28.x86_64

How reproducible:

Approximately one in ten sessions. I do not recall this happening 

Steps to Reproduce:
1. Choose "Logout" from Applications menu
2.
3.

Actual results:

The screen blanks (except for a single underscore as a cursor in the upper left corner), followed by a series of error messages:

Expected results:

Just an ordinary logout followed by the lightdm login screen

Additional info:

The system was upgraded to this version of the kernel (4.17.3-200) yesterday, and I do not recall seeing the problem before that, but I typically work under one login and just use su when I need to move between users, then just shut down when I'm finished for the day, so it's unusual to exercise the "logout" function.

Some possibly related bugs have been reported in the past, all related to drm but with different messages or Fedora versions. See:
#1393264
#1405811
#1534300
#1570880 (purports to have been fixed in kernel 4.16.5-300)

Comment 1 Laura Abbott 2018-10-01 21:14:52 UTC 
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 28 kernel bugs.
 
Fedora 28 has now been rebased to 4.18.10-300.fc28.  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 29, and are still experiencing this issue, please change the version to Fedora 29.
 
If you experience different issues, please open a new bug report for those.
Comment 2 BZ 2018-10-17 09:05:30 UTC 
After upgrading to the latest packages I've tried to reproduce this problem but have not been successful. Of course, it was never 100% reproducible, so it is possible that the problem simply hasn't manifested, or been hidden behind some other change, but as a first approximation it seems to be fixed... for now!
Comment 3 Jeremy Cline 2018-10-18 13:54:54 UTC 
Thanks for letting us know, I'll go ahead and close this for now :)
