This is the very same exact kernel, minus the patch in question:

Both previous kernel and this one have CONFIG_PCI_DEBUG=y.
This log excerpt shows that the ASMedia Thunderbolt controller
below the Intel Thunderbolt controller couldn't be enumerated
on boot:
mag 20 18:42:20 denis-pc kernel: pci 0000:03:01.0: broken device, retraining non-functional downstream link at 2.5GT/s
mag 20 18:42:20 denis-pc kernel: pci 0000:03:01.0: retraining failed
However, the Thunderbolt tunnel goes up and the devices are
enumerated 24 seconds later:
mag 20 18:42:44 denis-pc kernel: pcieport 0000:03:01.0: pciehp: Slot(1-1): Card present
mag 20 18:42:44 denis-pc kernel: pcieport 0000:03:01.0: pciehp: Slot(1-1): Link Up
Thanks,

Are you suggesting that the training failure is why there was an error?
If so maybe that should be cleared when it does eventually train.
