My tool chains are newer tho (11.1). Hmmm... I really don't see how calling a function or not can cause relocation overflow in other places. For the linker, all three setup_pcpu functions aren't that different. I'll set up a 11.0 system and see whether I can reproduce the problem. Just in case, can you please try to rebuild after mrproper? -- tejun
