Description Adam Williamson 2017-08-25 16:02:10 UTC 
I'm running Fedora 27 (future release) on my desktop, with an NVIDIA GeForce 9600 GT adapter, [10de:0622]. Running a GNOME desktop on Wayland, with fairly typical apps (Evolution, Firefox, gnome-terminal, hexchat). At least twice now my system has suddenly hung completely, with errors like this in the journal (on reboot):

The previous occurrence had lots of them, repeating over and over:
