I would say it doesn't even *try* to resume. I'm using a swapfile and I configured the kernel command line accordingly: BOOT_IMAGE=/boot/vmlinuz-2.6.32-19-generic root=UUID=f0e784ed-e140-4d73-87a3-8ef047012b9f ro reboot=bios,warm resume=UUID=f0e784ed-e140-4d73-87a3-8ef047012b9f resume_offset=29470720 vga=0x315 quiet splash also my /etc/initramfs-tools/conf.d/resume file should be correct: resume=UUID=f0e784ed-e140-4d73-87a3-8ef047012b9f resume_offset=29470720 Nevertheless, when the pc boots I always get this in my dmesg, regardless if it was a real clean boot or if it was a boot after an hibernation: [ 0.778970] PM: Checking image partition UUID=f0e784ed-e140-4d73-87a3-8ef047012b9f [ 0.785267] PM: Resume from disk failed. My notebook is a dell precision m6400 and hibernation used to work fine (with the same setup) in karmic. I tried myself to narrow down this problem and I came out with this conclusion: In /usr/share/initramfs-tools/scripts/local-premount/resume (which I suppose is used to see if a resume has to occur) there is a check on the type of hibernation (if any) happened with this line (almost at the end of the file): SWAPTYPE=$(wait-for-root "${resume}" ${RESUMEDELAY:-5}) It is my understanding (but I might be wrong) that the function "wait-for-root" can only check the partition whose UUID is passed as ${resume}, but it has no idea about the offset. So I think that it works only for swap partitions but not for swap files. I would like to make the hybernation/resume thing work for my laptop, so if I can be of any help testing things or if I can give any other info I'll be glad to do that.
