Code:

[39311.640600] PM: Image size after compression: -329949 kbytes

I believe the relevant hibernation settings are :

HIBERNATION=y
HIBERNATION_COMP_LZ4=n
HIBERNATION_COMP_LZO=y
HIBERNATION_DEF_COMP=lzo
HIBERNATION_SNAPSHOT_DEV=y

Has anyone seen negative image size? 20gb does not seem large for this system. I recently updated and have had trouble hibernating ever since.

I believe the negative size is indicating that I don't have enough swap space for hibernate. It seems likely that swap requirements have increased.
