Are you referring to "Initial fw_cfg support for qemu-x86 targets" ? I didn't find any patch in that email you sent to me. But I did give Seabios a try and it works. So I don't think there's anything wrong with the acpi tables generated by qemu. It seems other than just loading files into memory, guests are supposed to perform some "fix-ups" to those table according to qemu's instructions. But I can't say what's wrong without seeing your original patches. > > Anyways, I am sharing how you can test my patch to reproduce the error. > > 1.
