kernel for a Broadcom Swarm board

[Aurelien Jarno <aurelien@aurel32.net>]

Hi all,

We (Debian) have problems with Broadcom BCM91250A boards aka (Swarm) 
which do not boot with recent kernels. We tried 2.6.29 from linus tree 
and lmo, including with the swarm defconfig.

As those boards are installed remotely it is not really easy to do
debugging. That's why I am calling from help here.

Here is the boot log:

And then it hangs...

First of all, does someone have experienced the same problem? Any
patches floating around?

Alternatively I am interested to know about a not too old kernel version
(let's say >= 2.6.20) working for this board, and the associated .config
file. Thanks in advance.

Regards,
Aurelien
