I had a second thought this WE about a previous question from Sarah: my platforms do not have a PCIe extension slots to test other devices but the RN102 does have an additional device connected on the PCIe bus: a Marvell 88SE9170 SATA Controller. I have put below the output of lspci -vvv (on a 3.13.0-rc8 kernel w/ CONFIG_PCI_MSI enabled) in case you can spot something obviously wrong in it: 00:01.0 PCI bridge: Marvell Technology Group Ltd.
