diskless client can not be loaded (works at r224471)

Hi!

I use the same kernel for both host and diskless stations.
The FreeBSD-9 r224471 kernel at the host system works fine,
but the r224870 kernel oes not work. The file /pxeboot seems to be
loaded but then the host system does not answer to client's nfs
questions.

Here are the relevan parts of tcpdump logs at the host system (kaka is
the diskless station and 192.168.111.254 is the host system):
