[Launchpad Bug Tracker <1509355@xxxxxxxxxxxxxxxxxx>]

Suddenly and without any warning the screen became blank and lightdm
rebooted. I have found these interesting lines in dmesg:

[14137.598202] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
[14137.598222] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

[17123.949459] usb 1-2: USB disconnect, device number 9
[17794.824728] [drm:intel_dp_start_link_train [i915]] *ERROR* failed to enable link training
[17794.830525] [drm:intel_dp_complete_link_train [i915]] *ERROR* failed to start channel equalization

This *may* be related to screen switching (undocking/docking of the
notebook with an external monitor attached), but I am not sure at all.
