I use extlinux 5.11-pre3 compiled from buildroot.

I reproduced the problem under qemu.
The only difference between the two config is the addition of the line
"SERIAL 0 115200 0".

I need to test without SERIAL on the computer to confirm that the
problem comes there. (see also the report "6.01-pre 4 no timeout when
using serial")

Best regards,
Romain

Here is my configuration:

Contents of "boot_label" file
DEFAULT 1
---------------------------------------

Contents of "extlinux.conf" file
# ttyS0 115200 bps, no flow control
SERIAL 0 115200 0

# Enable menu.c32
UI menu.c32

# Disable the boot: prompt
PROMPT 0

# 5 sec
TIMEOUT 50

# 60 sec max
TOTALTIMEOUT 600

# Default boot label
INCLUDE boot_label

MENU TITLE Boot Menu

LABEL 1
   MENU LABEL System 1
   LINUX /bzImage_1
   APPEND console=ttyS0,115200

LABEL 2
   MENU LABEL System 2
   LINUX /bzImage_2
   APPEND quiet console=ttyS0,115200
