[SOLVED] No network at boot (Realtek RTL8111/8168/8411 + r8169)

Hello!

I've bought an old PC with 64-bits processor and Realtek RTL8111/8168/8411 (rev 02) ethernet controller. I have moved the SSD from my even older laptop with 32-bits processor into it. After 1m30 trying to run a start job for sys-subsystem-net-devices-eth0.device, which fails, it boots well except that (logically) the network doesn't work:

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:1f:d0:14:d3:1a brd ff:ff:ff:ff:ff:ff

$ systemctl status dhcpcd
● dhcpcd.service - dhcpcd on all interfaces
   Loaded: loaded (/usr/lib/systemd/system/dhcpcd.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

However I can start dhcpcd with systemctl by hand:

$ systemctl start dhcpcd

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

I've seen many posts on this forum reporting similar problems with this ethernet controller. As suggested here I have added the 'noapic' option to grub (via GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub + running 'grub-mkconfig -o /boot/grub/grub.cfg'). However I noticed that I can boot on a Ubuntu live-cd without this option and with the network working out of the box.

Here is part of the dmesg output.

$ dmesg | grep r816

Oddly enough, I also noted that the wallpaper of the login screen is not displayed. Except these two points it seems that everything works well (although it is a 32-bits system on a 64-bits computer).

Any idea? (Not on the wallpaper... ;-))

Only while typing the above post I noticed this "detail" that the architectures did not coincide, as I said.
Then I tried to boot from a 64-bit iso image of archlinux and it works out of the box, so my initial post is simply irrelevant!
Sorry for bothering...
