Comment 0 for bug 1990750

When starting the PC, the splash screen freezes with the motherboard logo displayed.
As my disk is encrypted the decryption filed does not appear below the logo.

By typing [ALT] + [CTRL] + [DEL] then the splash screen appears again followed by a start-up menu with the following line:
*Ubuntu
 Advanced options for Ubuntu

By selecting 'Advanced options for Ubuntu' the following submenu appears:
*Ubuntu, with Linux5.19.0-15-generic
 Ubuntu, with Linux5.19.0-15-generic (recovery mode)

Selecting the second option, then the system starts loading with the initial lines of code:
Loading Linux 5.19.0-15-generic ...
Loading initial ramdisk ...

When code has finished loading, the last line at the bottom of the screen is for unlocking the disk:
Begin: Mounting root fie system ... Begin Running /script/local-top ... Please unlock disk nvme0n1p3_crypt:

Then i type in the code and hit [return] and more code is loading, until a recovery menu with purple background appears, with the title:
Recovery Menu (filesystem state: read-only).

I select the first menu item:
resume Resume normal boot
and hit [return].

The menu changes to the notification:
You are now going to exit the recovery mode bla bla bla
with the [OK] button below it.

I hit the [OK] button and then the login screen finally appears.

I will post a video of the complete boot sequence later on as I need to install a softaware to edit the video.

It is noteworthy that on my previous Ubuntu 22.04 install the same issue with the frozen splash screen occurred when my system was updated with Kernel 5.15.5, but then I did not try out to execute the [ALT] + [CTRL] + [DEL] command.

Therefore the bug is probably affecting all kernels from 5.15.5 upwards.
