Bootpd problems with 2.4.x

[Patrick Caulfield]

I'm having trouble getting  bootpd to work on 2.4 kernels - the messages get
sent out onto the network but my DEC machines (Alpha 3000/300 and a
DECstation 2100) don't like them. It works fine on 2.2.19.

There's obviously nothing fundamentally wrong with the Linux server because it
can boot another Linux box using grub and bootp so there's something in the
replies that my DEC boxes don't like.

I've attached a couple of tcpdumps, does anyone have any ideas?
