I'm having trouble getting hibernation to work on my new Dell Inspiron 7590. It seems that the image is stored correctly (onto LUKS+LVM thin-lv), but resume fails, with the following left in the kernel logs: --- PM: Image signature found, resuming PM: resume from hibernation Freezing user space processes ... (elapsed 0.001 seconds) done. OOM killer disabled. PM: Marking nosave pages: [mem 0x00000000-0x00000fff] PM: Marking nosave pages: [mem 0x0009e000-0x0009efff] PM: Marking nosave pages: [mem 0x000a0000-0x000fffff] PM: Marking nosave pages: [mem 0x40000000-0x403fffff] PM: Marking nosave pages: [mem 0x66797000-0x66798fff] PM: Marking nosave pages: [mem 0x761f7000-0x791fefff] PM: Marking nosave pages: [mem 0x79200000-0xffffffff] PM: Basic memory bitmaps created PM: Using 3 thread(s) for decompression PM: Loading and decompressing image data (1343374 pages)...

PM: Basic memory bitmaps freed OOM killer enabled. Restarting tasks ... done. PM: resume from hibernation failed (-1) --- And then the system boots fresh. An internet search revealed absolutely nothing about the "Invalid LZO compressed length", and I've no idea why the image would be corrupt. I'd appreciate any ideas. Paul
