Description of problem: New as of today - PXE kickstart install hangs just after getting DHCP address. Last line: INFO : doing kickstart... setting it up Version-Release number of selected component (if applicable): 11.4.0.31
Can you ping the IP you expect the machine to have gotten at that point? Also, there are a few loops in the network address code that might have gotten fixed in the past day or so.
Works fine with today's (20080208) rawhide.
