I don't know anything about the kmemleaks mentioned elsewhere in this thread, but the idea of "stale PCI device info" seems possibly related to some acpiphp issues we've been working on recently. Starting with v3.9, we don't handle ACPI Bus Check notifications to host bridges correctly, and the result is that when we're using acpiphp, we don't notice when PCI devices are added or removed. There are more details in https://bugzilla.kernel.org/show_bug.cgi?id=57961 It looks like your Vostro 3550 uses acpiphp, so maybe there's a connection. Can you try a current Linus upstream kernel (v3.10-rc1 should be released in the next day or two) and apply the v3.10 patch from the bugzilla, and collect a complete dmesg log after you try a couple hotplug events?
