Description of problem: After undocking my laptop from my docking station, occasionally gnome-shell will appear to hang. Version-Release number of selected component (if applicable): gnome-shell-3.18.4-1.fc23.x86_64 kernel-4.4.6-300.fc23.x86_64 How reproducible: Intermittent Steps to Reproduce: 1. Undock laptop from docking station with active user session (logged in to GNOME, etc) Actual results: System appears to hang, no input via keyboard or mouse seems to take effect. Expected results: GNOME menubar at top of session should be redrawn on laptop display, system should accept input. Additional info: My laptop is a Lenovo Thinkpad T440s docked to an Ultradock with two monitors connected via DP. When I un-dock for the day, I typically only have GNOME Terminal running in my session, usually on one of the connected monitors. Sometimes everything just works normally when I un-dock; the terminal is re-drawn to the laptop display and I can continue to use it. However, often, this does not happen and my only recourse is to hard shutdown the laptop via the power button. There is a warning message in the journal from gnome-shell, but it doesn't appear to be a smoking gun.

This happened again last night when I un-docked. Instead of hard powering off, I closed the lid on the laptop and just let it do its thing. When I checked the journal this morning, I found a number of more interesting messages: Mar 30 17:20:23 mastershake kernel: [drm:intel_mst_pre_enable_dp [i915]] *ERROR* failed to allocate vcpi Mar 30 17:20:23 mastershake kernel: [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe A Mar 30 17:20:23 mastershake kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun Mar 30 17:20:23 mastershake kernel: ------------[ cut here ]------------ Mar 30 17:20:23 mastershake kernel: WARNING: CPU: 2 PID: 2544 at drivers/gpu/drm/i915/intel_display.c:12742 intel_atomic_commit+0xf1a/0x1420 [i915]() Mar 30 17:20:23 mastershake kernel: encoder detached but still enabled on pipe A.

I've updated the summary and changed the component as such.
Same problem here!
Is there a workaround for this issue?

I was having the exact same issue, so I updated to F24 to see if that would solve the issue. So far it seems to be fine, but since it is an intermittent issue I cannot be sure yet. If I get another hang I will update the issue here but so far things look promising.
Oh for completeness: kernel-4.5.5-300.fc24.x86_64 gnome-shell-3.20.2-1.fc24.x86_64
I can confirm this issue is solved for me with F-24, I haven't had the issue since updating.
I updated to kernel-4.5.5-201.fc23 from updates-testing and still had the issue. After upgrading to F24 my issue appears to be solved like Sander's.
Another confirmation that this issue doesn't seem to occur anymore with F24 (4.5.7-300.fc24.x86_64) Laptop: Lenovo T460
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
