Hi,

Thanks to Computer Enthusiastic for reporting this bug.
I've been hit too for quite a long time so I had to stick to an ancient 
kernel to keep the hibernation ability functional.
$ cat /etc/debian_version
bookworm/sid

$ dpkg -l linux-image-* | grep ^ii
ii  linux-image-5.10.0-13-amd64          5.10.106-1   amd64 Linux 5.10 
for 64-bit PCs (signed)
ii  linux-image-5.10.0-16-amd64          5.10.127-1   amd64 Linux 5.10 
for 64-bit PCs (signed)
ii  linux-image-5.18.0-4-amd64           5.18.16-1    amd64 Linux 5.18 
for 64-bit PCs (signed)
ii  linux-image-5.7.0-2-amd64            5.7.10-1     amd64 Linux 5.7 
for 64-bit PCs (signed)
ii  linux-image-5.7.0-3-amd64            5.7.17-1     amd64 Linux 5.7 
for 64-bit PCs (signed)

The kernel versions 5.7 executed the hibernation process properly.
The later ones did not until I had the init_on_alloc=0 to my grub 
parameters.
