Hi, I think there is a bug in qemu RTL8139.
RTL8139 uses: cpu_register_physical_memory(addr + 0, 0x100, s->rtl8139_mmio_io_addr); But in the comment of cpu_register_physical_memory() we have: "'size' must be a multiple of the target page size." And I think 0x100 is not a multiple of target page size.... :-P The attached patch corrects the problem.
