Boot process hangs when trying to boot with systemd enabled and using encrypted home

Hello, I've been able to reproduce on this two different machines. One is on bare metal running on an Intel NUC and the other is in a VM (2-core, 4GiB memory) both running MX Linux 19.2 x64 freshly installed and updated. I did a custom partitioning scheme where the primary was allocated for an unencrypted root, a second partition for an encrypted /home, and a swap partition.
Booting into the default sysvinit works as expected, I see a prompt for the decryption password, followed by the login screen. However, when I try to boot into the systemd kernel, the boot just hangs at the screen where it should ask for the decryption password. At this point, I need to do a hardware shutdown and reboot into the sysvinit kernel to get into the system. Is this bug or is there a workaround? Thanks.

Can you boot with SysV normally and post QSI ? (See my signature)

are there any messages on the screen "under" the boot splash (hit esc to view them)

When I select the systemd kernel and I press esc I see the following. Some of the text is cut off.

Code: Select all

[1.637835] piix4_smbus 0000:00:07.3: SMBus Host Controller n
[2.272597] sd 2:0:0:0: [sda] Assuming drive cache: write thr

Would this command show the same value twice:

Code: Select all

cat  /var/lib/dbus/machine-id  /etc/machine-id
If not, recreate freshly and reboot:

Code: Select all

sudo sh -c "rm  /var/lib/dbus/machine-id /etc/machine-id; dbus-uuidgen --ensure=/etc/machine-id ; dbus-uuidgen --ensure; "
EDIT +++
If you cannot see the luks-password prompt: Just type blindly the password and hit enter. At least it helps sometimes.

The first command showed that /var/lib/dbus/machine-id existed but /etc/machine-id did not exist.
The second command seems to have created a new machine-id in both locations.

Rebooting into the systemd kernel still does not show a password prompt.

Blindly typing in the decryption password and pressing enter does not cause the boot process to proceed.
