Yep, but the bug seems to be a displaced stack here; the information is
pushed correctly, but with an offset. Looking at FreeBSD interrupt code,
some exceptions have the tf_err value already pushed by the CPU, so no
need to do it twice.
I have sent a small patch to Paul for testing, it fixes the bug in my
VM. Hope that this fixes the bug natively too.
