How reproducible:
always

Steps to Reproduce:
1. the following is the pxeboot file:

DEFAULT pxeboot
TIMEOUT 20
PROMPT 0
LABEL pxeboot
KERNEL rhcos/images/latest/installer-kernel
APPEND ip=dhcp rd.neednet=1 initrd=rhcos/images/latest/installer-initramfs.img console=tty0 console=ttyS0 coreos.inst=yes coreos.inst.install_dev=sda coreos.inst.image_url=http://192.168.222.1:8000/rhcos/images/latest/metal-bios.raw.gz coreos.inst.ignition_url=http://192.168.222.1:8000/rhcos/ignitions/bootstrap.ign debug
IPAPPEND 2

2. boot server with pxeboot

3. 

Actual results:

after the rhcos is installed. the machine will restart and boot from disk. then the bootstrap enter the restart mode. 

since cannot ssh into the bootstrap rhcos. So very hard get the logs. please see picture. the machine will be there about 5 mins. and then be restarted with same behaviour

Expected results:

Additional info:

it worked  well with same config files when using 4.2 rhcos pxeboot image file.
after I download the 4.3 rhcos pxeboot image. always met this issue.
