This looks to be a PCI bridge that isn't working. Assuming this is
PCIe, connections between devices use a protocol to encapsulate
messages. The lowest layer of these is the Data Link Layer. This
message is saying the signalling required to start using the DLL never
completes. Once the OS is up, you might poke around via pciconf to see
if the device recovered, but given the damage to other hardware,
electrical damage seems like a reasonable conclusion here as well.
