Is this really a continuous section of the kernel log, no
lines removed from between?

If that is so, you are using user mode setting, which has been
depracated and removed a long time ago. No support whatsoever
in that case. KMS is mandatory, can you try with that?

What versions of the Nouveau components and the kernel you have?
What cards do you have?
