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:
