linux 4.15.0-20-generic messes up plymouth and no prompt for luks password

[Bump]

With 4.15.0-19-generic everything works perfect. However, with 4.15.0-20-generic, when I power on the computer, the kde plymouth does not show the textbox to enter the root volume crypts luks password. The logo just stays there like in the attachment.

If I uninstall plymouth and remove quiet and splash from GRUB_CMDLINE_LINUX_DEFAULT= && update-initramfs -u it boots in text-only mode and then can enter the password perfectly.

[Bump (bump55)]

All graphic fanciness should be removed by default by the way, it's only there to cause problems.

I can reinstall problematic packages to re-test but need specific instructions how to do is successfully.

[Joseph Salisbury (jsalisbury)]

Does this issue go away if you boot back into the -19 kernel?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

With the -19 kernel it works perfectly. I will try newest version asap.

The problem is with kernel linux-image-4.15.0-20-generic, with -19 works perfectly.

These are the steps to reproduce the issue:

1)

------------------ Start of /etc/default/grub -----------------

# /boot/grub/grub.cfg.

------------------ End of /etc/default/grub -----------------

The experienced issue is: when selecting kernel -20 to boot, it displays the following, and never progresses to ask for luks unlock password (other times just stays there the KDE logo but same thing, no textbox to enter luks password):
