    TW 32 bit has disappeared from own grub menu

    It happened after
    Code:
    zypper dup && reboot
    Tuesday. Only Memtest remains in TW grub menu.

    Multiboot with Debian 12.

    /boot is on separate partition because Debian's grub can't access btrfs.

    Code:
    # cat /etc/fstab
    UUID=SDA6_UUID  /                    btrfs  defaults                      0  0
    UUID=SDA6_UUID  /var                 btrfs  subvol=/@/var                 0  0
    UUID=SDA6_UUID  /usr/local           btrfs  subvol=/@/usr/local           0  0
    UUID=SDA6_UUID  /tmp                 btrfs  subvol=/@/tmp                 0  0
    UUID=SDA6_UUID  /srv                 btrfs  subvol=/@/srv                 0  0
    UUID=SDA6_UUID  /root                btrfs  subvol=/@/root                0  0
    UUID=SDA6_UUID  /opt                 btrfs  subvol=/@/opt                 0  0
    UUID=SDA6_UUID  /home                btrfs  subvol=/@/home                0  0
    UUID=SDA7_UUID  /boot/grub2  ext4   defaults  0  0
    UUID=SDA6_UUID  /.snapshots          btrfs  subvol=/@/.snapshots          0  0
    Code:
    # mount | egrep -v "cgroup|rpc|tmpfs|^sys|on /dev|on /proc|on /sys|on /var" | sort 
    /dev/sda6 on /home type btrfs (rw,relatime,space_cache,subvolid=264,subvol=/@/home)
    /dev/sda6 on /opt type btrfs (rw,relatime,space_cache,subvolid=263,subvol=/@/opt)

    /dev/sda6 on / type btrfs (rw,relatime,space_cache,subvolid=267,subvol=/@/.snapshots/1/snapshot)
    /dev/sda6 on /usr/local type btrfs (rw,relatime,space_cache,subvolid=259,subvol=/@/usr/local)
    /dev/sda7 on /boot/grub2 type ext4 (rw,relatime)
    gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,relatime,user_id=1000,group_id=100)
    I've tried from TW grub command line:
    Code:
    set root=(hd0,6)
    linux (hd0,7)/boot/vmlinuz-6.5.4-1-pae root=/dev/sda6
    initrd (hd0,7)/boot/initrd-6.5.4-1-pae 
    boot
    but
    Code:
    You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup.
    Give root password for maintenance
    (or press Control-D to continue)
    Reloading system manager configuration.
    Starting default.target.

    mount: /boot/grub2: unknown filesystem type 'ext4'.
    ...
    boot-grub2.mount: Failed with result 'exit-code'.
    Failed to mount /boot/grub2.
    Any idea please ?
