i see different output from the debug function everytime i change the source 
code and recompile the kernel. restarting the same binary results in the same 
unconverted instructions.

yes, the addresses make sense as i can see the unpatched instruction at that 
address in the disassembly and the instruction at these addresses are always:

add/sub rX, rY, #81000000

what do you mean by which kernel?
