Public bug reported:
I found a reason of non-functioning resume from hibernation when resume
partition/file is autodetected by intiramfs hook /usr/share/initramfs-
tools/hooks/resume.
Here is the scenario:
1) hook /usr/share/initramfs-tools/hooks/resume creates config
conf/conf.d/zz-resume-auto saved in initrd image, containing one variable:
RESUME=UUID=106238b0-707d-4422-866d-a7534da50702 in my case
2) during boot init script sets 'resume' variable to 'RESUME' value from
conf/conf.d/zz-resume-auto, then it executes local-premount scripts
including local-premount/resume
3) resuming script local-premount/resume
(/usr/share/initramfs-tools/scripts/local-premount/resume) tries to get resume
device major-minor numbers by these lines:
DEV=$(readlink ${resume})
DEV=/sys/class/block/${DEV##*/}/dev
if [ -r "$DEV" ]; then
read MAJMIN < "$DEV"
fi
4) next check fails and resume process silently aborts:
if [ -z "$MAJMIN" ]; then
exit 1
fi
Resuming script fails to get device major-minor because
resume=UUID=106238b0-707d-4422-866d-a7534da50702 -- it's not resolved
into device path in init script.
Commonly mentioned workaround is to explicitly specify kernel parameter
resume=UUID=106238b0-707d-4422-866d-a7534da50702 -- only in this case
init script resolves it to device path.
