I have no thoughts on why this would happen, but a workaround would be
to specify the configuration file with the pxelinux.configfile option.
pxelinux will go directly to the specified config file without trying
the 9 other possibilities. I wonder how many installations are really
able to overload IP address ranges with configuration information.

See:

for help setting a configuration file.
