I added the line "blacklist intel_hid" to /etc/modprobe.d/blacklist.conf and then ran
sudo update-grub sudo update-initramfs -c -k all and now hibernate works again (mostly -- hibernate works with "systemctl hibernate" and with closing the lid, but hibernate does not work with selecting hibernate from the gnome Power Off menu). I would be grateful for an explanation but I seem to be back in business in terms of hibernation.
