Description danny 2005-11-04 11:50:15 UTC 
	The motherboard is an Intel SE7320VP2, when booting diskless
	via PXE, it will porceed as far having to mount root via NFS,
	at which point, it gets stuck sending GETATTR packet but not seeing
	the answer from the server. Increasing the length of the ethernet
	cable (cat 5) overcomes the problem. This problem has been seen
	on three such motherboards.
	Booting an i32 kernel works fine.

Fix: 

using a longer cat-5 cable

The problem is not the cable length, nor em(4), nor amd64 but IPMI! 

when IPMI is enabled it will 'catch' packets to ports rx26f & 0x298
