Replacing the pxelinux.0 of 15.10 beta1 with the pxelinux.0 from 14.04 solves the problem of freezing, but then goes into boot: prompt after loading the config, since this versions config file contains config syntax the old code can't deal with.
So it's definitely the pxelinux.0 causing the freeze.
