Did you completely remove power-cord and wait 1 ~ 2 min. before
boot?

There are many Yukon II variants and each controller seems to
require special handling to work-around silicon bugs. And your
controller has a Audio Video Bridging (AVB) feature which may
or may not need a special handling in TX/RX path. At least it may
need to initialize or disable QoS specific feature of controller,
I guess. Unfortunately errata or detailed programming information
is not available to open source developers. 

Interrupt storm seems to indicate one of important event was not
properly handled in driver. Not sure what it is.

Sorry, have no further idea at this moment.
I hoped cold-boot shall put controller into compatible mode but it
seems it does not. I'll let you know if I happen to find a clue.
