Bug#1114894: OS-Prober generates not running entries for Debian 12

[Debian]

Package: grub2-common
Version: 2.12-9
Severity: important


Hello,

the OS-Prober does generate not running entries for Debian 12.
(Debian 8, 11 and 13 is working on other partitions.)

Instead of

     linux /boot/vmlinuz-6.1.0-39-amd64 
root=UUID=699e8929-8bdf-4b9f-9191-cf922ef52df3 ro quiet
     initrd /boot/initrd.img-6.1.0-39-amd64

this entry is generated, that ends somehow in a shell without starting 
the graphical interface

         linux /vmlinuz root=/dev/sda2
         initrd /initrd.img

The grub.cfg has been edited manually now and then it works for all 
different OS-versions.

Best regards
karsten
