Public bug reported: I'm running Ubuntu 21.04 on a laptop and have been using hibernate flawlessly for a couple of months. More recently, resuming from hibernation stopped working and now falls back to complete restart.
This is what I get from dmesg: [ 17.407048] kernel: PM: hibernation: resume from hibernation [ 17.409714] kernel: PM: hibernation: Marking nosave pages: [mem 0x00000000-0x00000fff] [ 17.409717] kernel: PM: hibernation: Marking nosave pages: [mem 0x0004f000-0x0004ffff] [ 17.409718] kernel: PM: hibernation: Marking nosave pages: [mem 0x0009e000-0x000fffff] [ 17.409721] kernel: PM: hibernation: Marking nosave pages: [mem 0xae6e9000-0xae6effff] [ 17.409723] kernel: PM: hibernation: Marking nosave pages: [mem 0xaf0cd000-0xaf5abfff] [ 17.409744] kernel: PM: hibernation: Marking nosave pages: [mem 0xb1e4c000-0xb1ed3fff] [ 17.409747] kernel: PM: hibernation: Marking nosave pages: [mem 0xb2698000-0xb2698fff] [ 17.409748] kernel: PM: hibernation: Marking nosave pages: [mem 0xb54af000-0xb54affff] [ 17.409749] kernel: PM: hibernation: Marking nosave pages: [mem 0xb54d8000-0xb54d8fff] [ 17.409751] kernel: PM: hibernation: Marking nosave pages: [mem 0xb7db3000-0xb7ffffff] [ 17.409761] kernel: PM: hibernation: Marking nosave pages: [mem 0xb8759000-0xb87fffff] [ 17.409765] kernel: PM: hibernation: Marking nosave pages: [mem 0xb8f9d000-0xb8ffffff] [ 17.409767] kernel: PM: hibernation: Marking nosave pages: [mem 0xba6f5000-0xba7fffff] [ 17.409773] kernel: PM: hibernation: Marking nosave pages: [mem 0xbbcec000-0xffffffff] [ 17.410626] kernel: PM: hibernation: Basic memory bitmaps created [ 17.481616] kernel: PM: Using 3 thread(s) for decompression [ 17.481620] kernel: PM: Loading and decompressing image data (835177 pages)...
