I haven't looked at this in a while but I remember reading the PCI
Express spec and deciding that interrupt messages sent after a posted
write cannot pass the write within the PCI Express world.  I thought
the issue is that once the PCI Express root complex has received the
interrupt message, it may process it and raise an interrupt with the
CPU before earlier writes have made through to memory.
