Hi,
The problem that I initially reported seems to be a compiler issues of some
sort.
# x86_64-unknown-linux-gnu-gcc --version
x86_64-unknown-linux-gnu-gcc (GCC) 4.0.2

Looking closer I see that Kouya Shimura has some patches relating
to change set 19175, the subject of that thread is
"fix iommu interrupt setup"
Using a different compiler, gcc (GCC) 4.2.4 (Ubuntu 4.2.4-1ubuntu3), I see
the problem that is being reported there. I will test the patches that
have been posted.
