[OpenWrt-Devel] Barrier Breaker 14.07-rc1

Hello all,
this is good news, however bad news is that brcm47xx (generic) target is
still seriously broken, at least on Asus WL-500W. The problem is
absolutely reproducible, and I reported it some time ago, but
unfortunately it attracted very little interest here for some reason.
Don't take me wrong, I use openwrt quite a lot for a long time on
various devices and value it high enough, but it's definitely beyond my
expertise to fix ethernet driver bugs and that sort of things, and
seeing broken images released for the second time (12.09 had similar
problem) is pretty strange.
Now back to the problem. The problem is, ethernet load causes kernel
oopses. In 12.09 it was "Unhandled kernel unaligned access", now in
14.07 it is "Unable to handle kernel paging request". The serial log
captured a few minutes ago from 14.07.rc1 is below. Usually I get this
oopses in maybe a minute or two after the routed traffic rises above say
15-20 MBit.
Additionally, there is now another (less important) problem. In 14.07
ethernet ports of WL-500W get initially configured as if it was e.g.
wl-500gp:
- WAN is assigned to eth0.2 instead of eth1.
- WAN6 is assigned to some "@wan".
- LAN ports does not include eth0.2 but they should (Its labelled LAN1).
(This is easily fixable by hand after installation as soon as you
identify what is wrong with this setup)
Thank you
Nikolai
