crysman, to advise, hibernate is supported. For more on this, please see
https://wiki.ubuntu.com/DebuggingKernelHibernate .

However, error messages in dmesg in itself does not constitute a bug, nor does it necessitate a report. For more on this, please see via a terminal:
man dmesg

If you have an actual usability/functionality issue, please file a new
report stating it precisely.

Title:
  nouveau error in dmesg + plenty of warnings

Status in xorg package in Ubuntu:
  Invalid

Bug description:
  Hi there, during hibernation I see some strange messages, but OK,
  hibernation is not officially supported.

  The problem is, that I've got errors in system log (dmesg) even
  without any hibernation, just normal boot from powered-off computer.

  Here is what I've got:
  $ dmesg | grep -iE "fault|error|warn" | grep -v default
