Hi Florian
1. change some configure[attach] as you said.
2. recompile the openwrt.
3. use the openwrt cross toolchain compile the 2.6.24 kernel.
4. the .24 kernel can boot to openwrt-rootfs.
5. but the .28 kernel can not.
so maybe there is nothing wrong with the toolchain.
there is something wrong with the .28 openwrt-kernel.
maybe there is something wrong with kernel FPU_EMU.

If your target CPU does not have a Floating Point Unit (FPU) or a
