Description Anton 2016-10-27 20:17:48 UTC 
Description of problem:
Hi, I'm experiencing random freezes while unlocking my workstation. I'm using Lenovo T460 laptop with Lenovo dock station which connects to 2 additional screens.

Version-Release number of selected component (if applicable):
4.7.9-200.fc24.x86_64


How reproducible:

Steps to Reproduce:
1. Connect to Lenovo docking station
2. Lock the system 
3. Try to unlock

Actual results:
Black screen, the computer is not responding (happens randomly, not every time)

Expected results:
The machine should wake and I should see login screen

Additional info:
This is the message I found in kernel log:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]]
Comment 1 Anton 2016-10-30 09:47:07 UTC 
The system froze while trying to reboot on docking station, found this in logs:

Comment 2 Gwendal 2017-03-20 16:23:38 UTC 
I also encounter (very frequent) random freezes when trying to unlock my lenovo T440s running Fedora 25, although it does not appear related to the docking stations. It also seems unrelated to X/Wayland.

Concretely: I open my lid, enter my password, press enter, and it never logs in: the login screen completely freezes. I can still move the mouse, but cannot interact with anything anymore. I can still press CTRL+SHIFT+F<number> to switch to a terminal.

Once it's frozen, my only solution is to reboot the system.

It may have a different root cause than this reported bug.
Comment 3 Justin M. Forbes 2017-04-11 14:45:05 UTC 
*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There are 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 24 kernel bugs.

Fedora 25 has now been rebased to 4.10.9-100.fc24.  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.
Comment 4 Justin M. Forbes 2017-04-28 17:17:58 UTC 
*********** MASS BUG UPDATE **************
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the 
relevant data from the latest kernel you are running and any data that might have been requested previously.
