Hi all,

I just compiled the kernel from wireless-testing git tree for my
gateworks avila ixp4xx board. I used the OpenWrt toolchain for cross
compiling for the arm - architecture and I used the .config of the
original kernel of OpenWrt (2.6.32-10)

The kernel hangs up directly after being uncompressed.

console output:

I don't know, how to debug such behaviour. Any suggestions would be
extremely helpful.
I attached my kernel config.
Thanks in advance

You should send this to the linux-arm-kernel(a)lists.infradead.org
mailing list.

FWIW, 2.6.35-rc1 boots fine on my ixp4xx NAS box.

You should also investigate if this is a regression from earlier
kernels or not. If you can't compile and boot earlier kernels
either then it may be a problem in your build tools or build procedure.
For starters, are you building with the correct endianess, and
are you sure you don't need a kernel shim to correct the bootloader's
machine type?
