Jan,
You're right, wrong again. I was thrown by the fact last "Xen WARN at
msi.c:636" prints no debug data, so I thought I had the sense wrong. I
don't know what happened to the last WARN's printks.
Anyway, here's output again, this time with msi.c as well so you can
correlate the line numbers without patching.
