Pierre's bug, he shared that extra bit about how it's checking for a
wrong UUID. It's possible I'm not cognitively grasping that the same
is mentioned in Bug #861057, but right now I'm not seeing that
referenced there. Maybe that was what was going on under the hood on
that closed bug, too..........

  I recently increased my swap partition size, and the wrong UUID
  was that of the old swap, and was set in the resume option of grub.cfg.
  After updating grub, this problem disappears, but anyway, the hibernate stuff in Debian
  seems really crazy:
  I found 3 different places where the resume can be defined
      /etc/uswsusp.conf
      /boot/grub.cfg
      /etc/initramfs-tools/conf.d/resume
  I tried all 3 together, with the following result

who can explain that?
It seems that the image was not written on disk when issuing the hibernate-disk command, but why ?
