Note. This problem appears itself if the swap partition is located on a regular partition of disk. Initramfs hook resume write `RESUME=UUID=someuuid` to the `conf/conf.d/zz-resume-auto`
If the swap partition is on a logical volume (e.g. LVM), then `conf/conf.d/zz-resume-auto` has a variable with a device `RESUME=/dev/commonvolumegroup/swap` and `/usr/share/initramfs- tools/scripts/local-premount/resume` works properly. This issue applies to both hibernation and hybrid sleep modes. Because hybrid sleep mode is a combination of both modes (S4+S3). -- 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/1957194 Title: resume from hibernation broken when resume image is autodetected another case Status in initramfs-tools package in Ubuntu: New Bug description: My issue very similar to https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1769297 I am assuming that the code at about line 162 in `/usr/share/initramfs-tools/init` like that: ``` resume=*) RESUME="${x#resume=}" case $RESUME in UUID=*) RESUME="/dev/disk/by-uuid/${RESUME#UUID=}" esac ;; ``` Only works if user wants to set resume partition as `UUID=some` at file like `/etc/initramfs-tools/conf.d/resume`. But in the case when initramfs hook resume automatically save `UUID=some` in initrd `conf/conf.d/zz-resume-auto` file it doesn't matter. Including for operate `DEV=$(readlink -f "$resume")` correctly in `/usr/share/initramfs-tools/scripts/local-premount/resume` Therefore I decide to add similar code to `/usr/share/initramfs- tools/scripts/local-premount/resume` to fix an issue with resuming.
