Sometimes Network service is started before udev renaming interface

Hello,

I've configured my Nuc D34010WYKH2 with a bridge static ip address (used for virtualization with qemu-kvm). Sometimes, when i reboot the network service fails to start because the network interface is not yet renamed.

Here is the systemd log :
http://www.filedropper.com/journalctl2

My network script /etc/systemd/system/network.service :
http://pastebin.archlinux.fr/501234

/etc/conf.d/network :
http://pastebin.archlinux.fr/501235

I have another problem like no hdmi sound and it seems i have acpi problems (system log)

I don't see any error messages in your systemD log file.

Looking at your ACPI messages, I don't see any apparent causes (but that does not indicate it is not).

Thank you for your reply.
My systemd log file was truncated by the pastebin website. I've reuploaded the file here : http://www.filedropper.com/journalctl2

That's odd. You would expect udev to settle before the rest continue's.

I have it, look at comment #6 here. You need to instantiate (systemD jargon for multiplex) an ifplugd service file from netctl.

A different alternative is to add the following to your section:

BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

I took these from the ifplugd service files. These are responsible for waiting after the device appears after it's rename. You need to replace %i with eno1, I think.

Could you post the output of:

cat /proc/asound/*

Good!

Check with alsamixer if your card is muted?

Re: Sometimes Network service is started before udev renaming interface

I've verified several times with gnome-alsamixer and my sound card is not muted.
I've also configured my sound card with pavucontrol. I've followed this how-to :
http://www.linux.com/learn/tutorials/76 … with-grunt

I have no hdmi sound with xbmc and vlc .
