Hello PVE community!

New to the forum, but I've been running PVE for - a while now in my homelab. Since the beginning of the year I think.

Until today I had a much older (cirka 2018) Windows Server 2016 machine running Hyper-V and a bunch of VMs that have now (finally) been migrated to the PVE instance, currently running on 8.4.1. The until-today Windows host (i7-8700k, Asus Prime H370M-Plus) is now transferred into a new case and has been outfitted with better OS/VM storage and, of course, PVE. The issue I'm having is with my dual 10 Gb SFP+ card. I have one in each server, and it has worked flawlessly both under Windows and PVE 8. But under PVE 9 I get the following message;
Code:

04:00.0 and 04:00.1 are the respective SFP+ ports on the card. The cards are Supermicro AOC-STGN-i2S (Intel 82599ES, same chip as X520 I believe).

I've searched around and the closest I've come to a possible solution is to add pcie_aspm=off to GRUB_CMDLINE_LINUX_DEFAULT. It did nothing, which is not very surprising considering ethtool -i just spits out Cannot get driver information: No such device. This makes me suspect that it's an issue with the ixgbe driver, but I have been known to jump to conclusions at times

I just installed PVE a few hours ago and I've done a post install update to PVE 9.0.10, kernel 6.14.11-3-pve.
