Wrong. I hope you've read the PCI spec. If not, you're going to look
silly shortly....
The spec quite clearly says that "Memory read transactions, ..., and
configuration transactions are non-posted". It goes on to give some
exceptions to this rule which do not include memory read transactions.
Therefore, your assertion that "all PCI transactions" are posted is
flawed.
