I manage eight Fedora 25 desktop machines of different makes which all are
updated in tandem. This morning I ran `sudo sh -c 'dnf update -y && reboot'` on
all of them, and two of them did not come back up. Based on the logs it appears
the problem is with libgtk-3.so.0.2200.11. From dmesg on machine 1:

gnome-session-f[5292]: segfault at 0 ip 00007f46a0aa94e9 sp 00007ffc4b398840
error 4 in libgtk-3.so.0.2200.11[7f46a07ca000+6f9000]
gnome-session-f[5713]: segfault at 0 ip 00007fdc1d4a54e9 sp 00007ffce01ed260
error 4 in libgtk-3.so.0.2200.11[7fdc1d1c6000+6f9000]

On machine 2:

gnome-session-f[3160]: segfault at 0 ip 00007f2ea97674e9 sp 00007ffc23562d80
error 4 in libgtk-3.so.0.2200.11[7f2ea9488000+6f9000]

Workaround: Downgrade the Nouveau driver:

sudo dnf install xorg-x11-drv-nouveau-1\:1.0.13-1.fc25.x86_64

Worked for both machines.
