Comment 0 for bug 2008892

After running the 22.04 installer, my laptop would restart and after seeing the initial loading screen I'm dropped to a busybox shell. It makes no difference what boot option I use from my UEFI or installing with or without disk encrpytion.

The installer finds my disk without problems, but afer rebooting the Ubuntu screen hangs for around a minute before dropping me into a busybox shell.

In this shell I do the following:

```
# ls /dev/mapper
control isw_behfgagfc_ASUS_OS

# kpartx -av /dev/mapper/isw_behfgagfc_ASUS_OS
add map isw_behfgagfc_ASUS_OS1 (253:1): 0 1048576 linear 253:0 2048
add map isw_behfgagfc_ASUS_OS2 (253:2): 0 3500032 linear 253:0 1050624
add map isw_behfgagfc_ASUS_OS3 (253:3): 0 495579136 linear 253:0 4550656

# cryptsetup luksOpen /dev/mapper/isw_behfgagfc_ASUS_OS3 WHYEVER
Enter passphrase for /dev/mapper/isw_behfgagfc_ASUS_OS3: ***

# exit
```

After which the Ubuntu loading screen re-appears and I have to enter the disk decrypt key again. Then my system boots fine, but I think it's a bug to have these commands to manually `kpartx` every time.

If I install without disk-encryption, I still have to run "kpartx -av /dev/mapper/isw_behfgagfc_ASUS_OS" in the busybox shell before I'm able to continue.

Attached the log from apport inside the finally booted Ubuntu installation with disk-encryption on.
