While I'm trying to find the proper terminal command to check the process list you can click the percentage near CPU LOAD field and tell me what eats cpu. Is it sirq?

Try 'top' and make your terminal screen as tall as possible.

Download puTTY here http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html and connect to the router via SSH (don't forget to enable ssh server here http://my.router/Advanced_System_Content.asp ). Login with your usual username and password and enter top command. That way you'll see what's eating cpu.
Also is there any reason for you to bother about 2.x kernel? It is still there only for specific purposes as I said before. It is deprecated as of now and soon will be dropped. Use 3.x
OK, put 3.x kernel back, partial PUTTY output. Very high CPU usage, see screen capture.

======================
Looks like the DLNA is doing it... but it wasn't on the 1.x kernel?
DLNA takes a lot of CPU when it does it's initial index, but it doesn't effect the router performance. It will release the CPU if something else requires more CPU at that time (prioritized multitasking). But as you found it will quiet down when it's done. It's normal.
The 1.x kernal and the process monitor didn't really report everything properly in the Web GUI. But if you ran the 'top' command it would show up that DLNA was busy with it's initial indexing.
It could have been an iPad problem for all I know?
I do not know if its an Ipad or a firmware issue but I do know that 1.1.2.3-010 was the last version that worked well with my Ipad3.
Great work guys, hopefully IPv6 is rock stable. I have a question, is there ANY way to have a scheduled WAN shutdown and WAN turnon in the gui? Or an external script for it? I know wireless is available but my needs are a complete scheduled WAN connection. Thanks
