Title:
Ability to hibernate lost after update of kernel version
Status in linux package in Ubuntu:
Expired
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.

7th July:
Sorry to say that I have meanwhile (after a restoration of my root partition
to kernel version 5.4.0-74) figured out that the above error
"hibernate:Warning: Tuxonice binary signature file not found."
does not come from the kernel update (to -77) but seemingly from my
repartioning.
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.
