We are building a very large hierarchical PCI System using the Intel 21154
PCI bridge. I have noticed the following behavior. If the bridge receives a
retry on a 64- bit data transaction it will retry the transaction with Req.
64 negated this could cause a problem with other bridges or targets that now
expect 64 bit data transfers. Has any one seen this and is there any
workaround ?
