When running on Intel we emulate real mode using vm86 mode. This mode
requires ds.base == ds.selector << 4, which isn't the case here. You
can modify the code to satisfy this requirement, or you can try the
emulate_invalid_guest_state=1 module parameter (which will likely fail
since it is not completely implemented).
