It's likely due to the exception vectors rewrite, and yes it's an assembler issue (what's your binutils version?). Your errors look like they're coming from LOAD_HANDLER(). For some reason it seems to be interpreting the immediate as signed, or the actual calculation ends up being negative, neither of which should happen. It might take a bit of trial and error, and the assembler doesn't give a lot of good options to debug it, so if I can reproduce it here with your bintuils version it will be helpful. Thanks, Nick
