You will need to disassemble your minios kernel and see which instruction is at 0x56fc8. (Chances are, it will be `jmp %r15`). The content of %r15 looks like x86 opcode, which is reminiscent of the XTF relocatability bugs. Make doubly sure you are compiling with -fno-pic and link with -no-pie. ~Andrew
