Moin, ich habe mir den "13-Watt-PC: Sparsamer Allrounder" aus der c't Reihe Der Optimale PC zusammengebaut. Das läuft mit der aktuellen Proxmox Version (VE 7.3) auch alles soweit ganz gut. Sobald ich aber die Grafikkarte einstecke, fällt der LAN-Port beim Boot weg. Ziehe ich den 8-poligen Stromstecker von der Karte ab, läuft wieder alles noprmal.
Die erste Vermutung, eines Zusammenhangs mit der Kernelversion (5.15) bestätigte sich aber nicht. Auch eine Installation von 5.19 und 6.1 behebt das Problem nicht.

Mainboard: GIGABYTE B660M Gaming X AX DDR4 (Rev. 1.0) | LAN-Chip: RTL8125B
Grafikkarte: ASRock Radeon RX 6600 Challenger D, RX6600 CLD 8G, 8GB GDDR6, HDMI, 3x DP (90-GA2RZZ-00UANF)

Mein bisheriges Suchen seit einigen Tagen brachte leider keine direkt vergleichbaren dokumentierten Probleme im Netz. Daher der Versuch ob hier ggf. jemand eine Idee oder einen Tipp hat.


Code:
Linux abakus-pmx1 6.1.0-1-pve #1 SMP PREEMPT_DYNAMIC PVE 6.1.0-1 (Tue, 13 Dec 2022 15:08:53 +0 x86_64 GNU/Linux

lspci -v zeigt die Grafikkarte und die LAN-Karte soweit ich das sehe korrekt an:

nehme an, dass sich die PCI Adressen durch die GPU verändert haben und dadurch die Netzwerkkarte jetzt schlicht anders heißt - siehe:
https://forum.proxmox.com/threads/e...-boot-no-access-to-proxmox.96483/#post-418018

-> einfach in /etc/network/interfaces den Namen anpassen
Ich hoffe das hilft!
Die Annahme war korrekt, aber Anpassen alleine half nicht. Bevor ich lange suche und weiter wilde Sachen mit dem System mache, habe ich kurz neu installiert MIT der Karte drin, und alles läuft wie es soll. Vielen, vielen Dank!

Freut zu lesen, dass es dann doch geklappt hat :)
