Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.
We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures. At a minimum, we need: 1. The specific steps or actions you took that caused you to encounter the problem. 2. The behavior you expected. 3. The behavior you actually encountered (in as much detail as possible). Please also ensure that you include the release and flavour of Ubuntu that you are using. Thank you! (Firstly you say it was due to an updated kernel, then related to a change you made to partitioning... Please correct your bug report so it reports only what your actual problem is without having to read through update threads that can be confusing). ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1934462 Title: Ability to hibernate lost after update of kernel version Status in linux package in Ubuntu: Incomplete Bug description: Hi! I have Ubuntu 18.04 installed (due to Petalinux requirement) where Hibernation so far at least worked. Recently I got an update notification, confirmed it and am now running on this version: $ uname -a Linux datatel-XMG-CORE-M19-GTX-1650 5.4.0-77-generic #86~18.04.1-Ubuntu SMP Fri Jun 18 01:23:22 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Before the update, using kernel 5.4.0.74 a "sudo hibernate" worked fine. Now it does not, instead returns a black screen for a sec and then this notice: hibernate:Warning: Tuxonice binary signature file not found. In addition the system hangs for a couple of seconds. Looking for help on that I saw several posts proposing to adapt /sys/power/state, adding "disk" and "standby" to it. I have tried that in any possible way I could think of, using vi directly on the file (as su), writing it with an "echo... > /sys/power/state" command, making up a file in my home and then copying to that location using "sudo cp ~/<file> /sys/power/state". Neither of this works. I always get a permission error. I have even tried to "chmod" all the directories to "777" and that was successful looking at "ls -la" but won't help either. Maybe I should mention that my Ubuntu installation resides on a USB- Stick. I posted this on Ask Ubuntu and was asked to file a bug report. So here you are. Thanks.

What I did: I have a 256GB SanDisk USB stick where I installed Ubuntu 18.04.04 . Partitioning was: /dev/sda1 fat32 /efi 1,4G /dev/sda2 fat32 /mnt/UDISK 55,6G /dev/sda3 ext4 / 140G /dev/sda4 swap 35,9G I made a backup of sda3 with dd deleted sda2 und sda3 with gparted and increased the size of sda2 to the max then, partitioning: /dev/sda1 fat32 /efi 1,4G /dev/sda2 ext4 / 195,6G /dev/sda4 swap 35,9G I restored (former) sda3 to now sda2 tried to reboot, got a boot problem because /etc/fstab still contained the old sda2 entry, removed that and the system booted apparently normal. Then I made a "sudo resize2fs /dev/sda2" to get the full size of the partition for the file system and it seemed to work fine. BUT: Now hibernation does not work any more and produces the above error - before the Software Updater came forward.
