So i recently got my PLX88096 chip in the mail, and have used it to install 4 R9700 AI’s onto the system, however it seems my poor prosumer grade AM4 X570-D4U-2L2T/BCM motherboard has had enough of my shenanigans and just doesnt have the BAR space to deal with it
My onboard 10Gbe also stopped working, but i suspect this is just a side effect of the lack of BAR space
I’ve added the Dmesg logs and my kernel opts
Please obi-wan janitobi’s, you guys are my only hope:
Kernel Args:

For your viewing pleasure(or distaste, depending on tolerance):
