So, the offending commit seems to be

https://github.com/systemd/systemd/commit/17c40b3a8fbfb797110c88d749bd5d37e6ee6e3c#diff-f1a8ef48b9daffd7280cdacb9044c80f

I'm bringing Mario into the loop here, the author of this commit.
Mario, please see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902416 for the
complete bug report.
Do you have any idea why this commit could break hibernate/resume for Joel?

Joel, I see you have multiple swap partitons defined in
https://bugs.debian.org/cgi-bin/bugreport.cgi?att=4;bug=902416;filename=fstab;msg=5

Which one of those is setup as your resume partition in
/etc/initramfs-tools/conf.d/resume?

Mario, could the systemd code be confused by the existence of two swap
partitions and pick the wrong one?
