The error is coming from sky2_err_intr, not sky2_hw_intr:
sky2 0000:06:00.0: error interrupt status=0x40000008 sky2 0000:06:00.0: error interrupt status=0x8
Also, fwiw, when running with vt-d disabled, I don't get the dhcpinform/ack messages, but continue to get the interrupt status messages. That said, I am not certain the the dhcpinform/ack is related at to the sky2 issue.
