From a07a531329b1c5cfb74e94ae5a74853fb96cf541 Mon Sep 17 00:00:00 2001 From: Jakob Haufe Date: Mon, 22 Jul 2024 20:53:47 +0200 Subject: [PATCH] octeon: ubnt-edgerouter: Disable PCIe Some devices lock up on PCIe initialization: [ 64.309697] PCIe: Port 0 in endpoint mode, skipping. [ 64.320496] PCIe: Initializing port 1 [ 64.325257] PCIe: BIST FAILED for port 1 (0xffffffffffffffff) (system hangs here) Given the ER contains no PCIe peripherals, has no way to attach any and the stock kernel doesn't have PCIe support either, just disable it.
