8.2i EDK SP1 - "opb_pci_v1_02_a" bridge hangs with slow PCI clock during Configuration Read


When the PCI clock is slow relative to the OPB clock (300ns PCI, 10ns OPB), the bridge hangs on a configuration read of the Latency Timer during self configuration. Previous configuration reads of the status and command register complete.

The first service pack containing the fix is EDK 8.2i Service Pack 1.
