Public bug reported:
No idea what caused this.
I booted the machine, logged in, started the Software Updater to check for
updates and then walked away. When I got back, Software Updater said it had
failed to download repository information. I told it to retry, and about that
time I got the notification that something had crashed.
I see the stack trace mentions nouveau and hotplug. I did not plug/unplug any
external monitors or do anything other than what was mentioned above before
this Oops happened.
