Description of problem:

After upgrading my Thinkpad X201s from Fedora 25 to 26, it always locks up within 30 minutes of booting into GNOME with either Xorg or Wayland.  

There is nothing in journalctl at the time of the crash (rsyslog seems to have stopped logging after the upgrade, haven't investigated that yet).  However, I do see this sometime between booting and the crash every time it happened:

Jul 12 15:10:48 laptop kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
Jul 12 15:10:48 laptop kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

I also saw the lower half of my screen flicker black while changing workspaces or moving windows a few times priror to the crash, each time.  This is what led me to suspect a video-related problem in the first place.  I'm not 100% sure the problem is in -drv-intel, but it seems the most likely candidate.

Downgrading xorg to the version shipped with F25 seems to have made the problem go away in X (haven't tested Wayland yet).

Side note:  I also tried downgrading the kernel with no change, and libdrm, which caused GNOME to fail to start.
Comment 1 Bernard 2017-08-05 20:21:26 EDT
I had a very similar problem, only with GNOME on Wayland sessions, in Fedora 24, and 25, on a ThinkPad X201. I have not reproduced it on Fedora 26 so far. (I have not tested GNOME on X11 sessions on Fedora 26, only Wayland sessions.)

I reported the bug here: https://bugzilla.redhat.com/show_bug.cgi?id=1408332

This other bug report may also be the same problem: https://bugzilla.redhat.com/show_bug.cgi?id=1412469
