Description matt 2000-03-16 19:20:01 UTC 
The box bootp's off a master FreeBSD NFS server.  When the Alpha box first starts, link and activity lights work.  The box bootp's, starts netboot, then loads the kernel.

As soon as the kernel starts, the link and activity lights dissapear.  The dc driver detects the dual onboard 21143 based 10/100 Ethernet:

dc0: <Intel 21143 10/100BaseTX> port 0x1100-0x117f mem 0x20c2000-0x20c23ff irq 29 at device 9.0 on pci0
dc0: interrupting at TSUNAMI irq 29
dc0: Ethernet address: 08:00:2b:86:28:54
miibus0: <MII bus> on dc0
dcphy0: <Intel 21143 NWAY media interface> on miibus0
dcphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

The link lights never come back on, nor any activity lights.  We have stacks of these boxes, and link lights are necessary for first level debugging. (bad cabling, etc)

This is not exclusive to a box booted via. bootp.  A box started via. local disk also exhibits this problem.

Fix: 

No known cure.
How-To-Repeat: Boot the kernel.
