Hello,
in line with an composition we would need more information about the partition structure and content that is used when Linux does hibernation (suspend to disk). Does anybody have a tip where we can get documentation on this?
Thanks in advance

It has to be a normal swap partition or a swap file located on a regular
parition (see Documentation/power/swsusp-and-swap-files.txt in the kernel
tree for some information about how swap files are used).
Thanks,
Rafael

Linux doesn't have hibernation partitions. It has support for swap
partitions and swap files on normal filesystems, which can be used to
page out memory during the normal running of the system. Hibernation in
Linux uses available space in this area for writing the hibernation image.

Nigel
