Won't boot with 2.5GBe PCIe adaptor connected

[voltagex]

Hi,
I'm able to plug in a TP-Link Gigabit adapter and the board boots fine, but with a Diewu 2.5 gig adapter I get a hang at "booting Linux". I'm not able to get any other output (although assistance with earlyprintk/earlycon parameters is welcome)

The adapter is this one: https://www.aliexpress.com/item/4000150903887.html

I've tried both with the "stock" 2017 u-boot and with a newer 2020.07 based one, both with Armbian and ayufan images to no avail.

hotplug or boot with blacklisted module and see what happens during insertion
