>Description:

	I have an amd64 machine that will work just dandy when running
	a 2.1 kernel.  The machine is diskless and netboots, without
	any problems.

	A 3.0 or a -current kernel will not netboot.  They will properly
	pxeboot and start loading the kernel, but when the kernel tries
	to get a dhcp lease, it will time out.

	The problem is described in

	http://mail-index.netbsd.org/port-amd64/2006/02/07/0001.html
	http://mail-index.netbsd.org/port-amd64/2006/02/23/0003.html

	Note: the problem also exists on port-i386.

	The network interface in question is a bge (onboard).

	Below is the dmesg of the 2.1 kernel:

	Take a 3.0 kernel and try to netboot it.
