Hi Bjorn, > Can you open a report at http://bugzilla.kernel.org, category > drivers/PCI, and attach complete "lspci -vv" output (run as root) and > complete dmesg logs, both when hub is attached at boot, and when > booting without hub and attaching hub later? > > I don't know much about Thunderbolt. But since it appears as a PCI > device, I would expect some sort of hotplug notification when you > attach the hub. If pciehp handles hotplug, it looks like we should > see something from pcie_isr() in the dmesg log. > > Since you don't see that, I suspect we're getting ACPI notifications > via the acpiphp driver. I'm not as familiar with that, so I don't > know what if anything it logs. If you're inclined, you could add some > printks in > > acpiphp_add_context() > acpi_device_hotplug() > acpiphp_hotplug_notify() > hotplug_event() > > Then we'd at least see if we get any ACPI notifications. > > Bjorn I've logged a report with the requested details; it can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=115121 Kind regards, Jack
