The way to see this bug is just try to compile the MIPS kernel (either
2.4.1 or 2.4.3) as follows:

1) make distclean
2) copy linux/arch/mips/defconfig-malta linux/.config
3) make oldconfig
4) make menuconfig
5) change the endianess from little to big
6) make dep 
7) make zImage 

That is a kernel bug. The code only works on littl endian by accident
Here is a patch.
