Description Adam Williamson 2016-10-06 22:32:23 UTC
Recently my desktop - running Fedora 25, kernel 4.8.0-0.rc8.git0.1.fc25.x86_64 , xorg-x11-drv-nouveau-1.0.13-1.fc25.x86_64 - hung in the middle of normal operation. X was totally stuck, but I could get in and shut down via ssh. The journal shows these nouveau errors at the time of the hang:
