Public bug reported: Ubuntu 16.04 32-bit In fstab I have: UUID=38e6603c-6b17-488a-9613-7341e8e89274 none swap sw 0 0 But I have 2 swap partitions on my hard drive, the other for a 64-bit instance. With this setting, suspend-to-disk (STD) was functional in ~ 50 % of the cases. Then I created /etc/initramfs-tools/conf.d/resume with: RESUME=UUID=38e6603c-6b17-488a-9613-7341e8e89274 and did sudo update-initramfs -u -k all. After this, the STD never worked again. So I extracted /boot/initrd.img-4.4.0-78-generic and saw the surprising content, different from the swap-partitions UUID: RESUME=UUID=93782983-700c-4084-84b1-5e3f8c1e788f Another try of sudo update-initramfs -u -k all created another random UUID, both do not match with any partition UUID on my system.
So I recovered my original system back from a backup image and discovered in conf/conf.d/resume from /boot/initrd.img-4.4.0-78-generic: RESUME=UUID=38e6603c-6b17-488a-9613-7341e8e89274 So originally there was the correct UUID, even I never created a /etc/initramfs-tools/conf.d/resume file. Now I do not have any idea, why sudo update-initramfs -u -k all doesn't create correct values to make STD always working reliably. ** Affects: initramfs-tools (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1692225 Title: update-initramfs -u fails with random resume UUID Status in initramfs-tools package in Ubuntu: New Bug description: Ubuntu 16.04 32-bit In fstab I have: UUID=38e6603c-6b17-488a-9613-7341e8e89274 none swap sw 0 0 But I have 2 swap partitions on my hard drive, the other for a 64-bit instance.
