Which DHCP server do you use? IIRC there was this problem that some
DHCP replied in a strange way, which ipconfig can not read.

ipconfig has no man page, but a README describing the option is
included in the sources. Have a look at the sources of the klibc-utils

This may be the TFTP request from the network card itself (for
receiving the linux kernel and initrd). But after this the kernel and
the initrd is requesting the IP address again.

P.S. If your machine is connected to a CISCO switch, this may also
cause problems. If the autonegotiation (maybe also the spanning tree
thing /fastport attribute) takes too long, the linux kernel may want
to reset the network device before it tries to use it again.
