I tried to reproduce it in a Ubuntu 22.04 VM by preparing disks with following options:

```
sudo apt install cryptsetup-bin cryptsetup-initramfs
sudo cryptsetup luksFormat --cipher=aes-cbc-essiv:sha256 --hash=sha1 /dev/vdb
sudo cryptsetup luksFormat --cipher=aes-cbc-essiv:sha256 /dev/vdc
sudo cryptsetup luksFormat --hash=sha1 /dev/vdd
```

Then added break=bottom to the kernel options:

```
sudo vim /etc/default/grub
-> GRUB_CMDLINE_LINUX_DEFAULT="quiet splash break=bottom"
sudo update-grub
```

Rebooted and tried to open the disks in the initramfs:

```
cryptsetup luksOpen /dev/vdb vdb
cryptsetup luksOpen /dev/vdc vdc
cryptsetup luksOpen /dev/vdd vdd
```

All opened fine. Need to further investigate. It does look like it's the cipher mode or hash spec.
