No issues with fresh boot, however after resume from suspend I see these messages -

Device 8893 (rev 52) (prog-if 01 [Subtractive decode]) Physical Slot: 5 Flags: bus master, fast devsel, latency 0 Bus: primary=02, secondary=03, subordinate=03, sec-latency=64 Capabilities: [90] Power Management version 2 Capabilities: [a0] Subsystem: Hewlett-Packard Company Device 1905 After resume the sec-latency is set to 128 instead of 64. This seems to be VTd related - as if I disable VTd in BIOS the message doesn't appear. I saw an older commit which to me looked liked it fixed a similar issue - PCI : Calculate right add_size commit a4ac9fea016fc5c09227eb479bd35e34978323a4 upstream. During debug of one SRIOV enabled hotplug device, we found found that add_size is not passed properly. I am running Ubuntu daily mainline build from couple days ago - I think it should include the above commit. Let me know if more info is needed - I don't see any issues because of these but that may be because I am not using VTd for anything.
