Description
Exact same issue as this ticket:
/ticket/6819.html
During bootup there is a very large period of time (~10 seconds?) where LAN clients can pull a DHCP lease from an upstream router connected to the WAN port.
dmesg from Attitude Adjustment 12.09 RC1:

This issue is present in Attitude Adjustment but appears to be gone in trunk.

Correction of my last correction: I dug up some old builds based on r32735 and the problem existed there, so I can't say for sure that it ever worked correctly :-(
I'll give US$500 to the person that squashes this bug.

Replying to brnt:
To correct my correction of my previous correction... :-|
The earlier rev indeed didn't suffer from the issue. I whittled my way down to the rev where the issue was introduced (r33301; r33300 is fine) and diffed the two. Attached is a patch that applies the important stuff to trunk (r36698).
How could one make a patch for Attitude Adjustment?
I hope this fix gets backported to AA. This is a serious issue affecting the 3052 platform.

Is there a reason to why the patch attached has not been accepted yet? It still does the job in 14.07 final.
The same issue affects another rt3052-based router, the ReadyNet WRT300N-RN.
