problem upgrading from 11.3 to 11.4 (loader init_state not found)

[Patrick Lamaiziere]

Hello,

We upgraded a virtual machine from 11.3-release-pX to 11.4-release via
freebsd-update.

Since, the vm does not boot, the loader shows an incomplete menu with an
error : "Options: init_state(heart character) not found"

I put a photo here :

Then if we type "boot" the machine boots properly.

The menu looks like :
---Welcome to FreeBSD----
1 <-[-11xxxx;6H. <-[-1107xxxx;8HYES

Options: init_state not found
Error while including /boot/menu.rc on the line: menu-display

Can't load 'kernel'
Type '?' for a list of commands, 'help' for more detailled help
-----------

/boot/loader.conf:
# divers
loader_logo=beastie
loader_color="YES"

# modules
tcpmd5_load="YES"

I read in /usr/src/UPDATING that there were some changes on the loader
but /boot/loader is the same file as /boot/loader.4th so that looks
good.

Any clue ? 

Thanks regards.
