Stuck at scheme prompt when booting

Subject: Stuck at scheme prompt when booting

I have run into a problem with booting a computer that is running the
Guix operating system.

After entering the passphrase when prompted with:

> Enter passphrase for /dev/sda1:

I end up at this prompt:

> scheme@(guile-user)>

and the system does not continue to boot.

I have not made any changes to my system configuration to cause this

Below is the sequence that results in me getting the
"scheme@(guile-user)>" prompt.

In the output below it says "',q' to continue" but when I do that at
this prompt I am greeted there is a lot of output with the last line
of the output saying:

> ---[ end Kernel panic - not syncing: Attempted to kill init! exit
>  code=0x00000000 ]---

Is there something I need to enter at this scheme prompt to continue
with the booting this computer?

If there is not a way to continue booting this computer from this
scheme prompt how should I attempt data recovery from the encrypted
hard drive?

Any help with this would be appreciated.

Thank you


1) I push the power button to power on the system.

2) It says:

> Grub loading..  Welcome to GRUB!  Attempting to decrypt master
> key...  Enter passphrase for hd0,msdos1
> (lone-string-hexadecimal-characters):

3) I enter the passphrase

4) It says: "Slot 0 opened"

5) The Grub menu is displayed

6) I do nothing and it continues after the grub timer finishes
counting down.

7) These messages are displayed:

8) Then it prompts me for a passphrase:

> Enter passphrase for /dev/sda1:

9a) If I deliberately enter the wrong passphrase it says:

> No key available with this passphrase.  Enter passphrase for
> /dev/sda1:

9b) If I enter the right passphrase it says:
