Hi,

I have kernel 2.6.32 with codesourcery eabi (arm-none-eabi )working
ok, booting,
but I have change toolchain to codesourcery 2011 gnu/linux (arm-none-
linux-gnueabi) and now after
uncompressing hang.... I need change this for buildroot ...

Uncompressing
Linux........................................................................................................................................................
done, booting the kernel.

p.s I do not exactly understand difference between EABI and GNU/
Linux....
