That could means, that the Kernel has been decompressed successfully and 
is most likely failing to find some memory...

just compile the Kernel with debug informations (e.g. -ggdb) and then 
connected to the gdb to your BDI and look where the Kernel is working.

it ist possibel, that the board information you set for the pxa255 is 
not correct. Set a breakpoint to the start address of the Kernel an look 
at the board info structure pointer (ppc = r3) and verify if it contains 
the right values for your board.
