[Solved] Resume after suspend/hibernation looses eth0 connection

Hi,

I started using new Devuan machine (beowulf/ceres) a week ago. It has annoying network disconnection problem after resume, which I had gotten so used from old Linux system.

I followed one troubleshooting guide by creating a unload_modules file. But it did not solve the problem.

/etc/pm/config.d$

What happens when you use ifconfig to manually configure your Ethernet device with an IP address and netmask instead of asking DHCP to do it? Can you ping anything by ip address then?

I believe that Devuan is based on Debian Buster. If something doesn't work in Buster, it probably won't work in Devuan either without tweaking.

Rather than restarting the service just bring the interface down then back up again:

# ifdown eth0
# ifup eth0

^ If that works then create an exectuable script at /etc/pm/sleep.d/00fix with this content:

#!/bin/sh
#
# 00fix: bring network back after resuming from suspend

case "$1" in
   thaw|resume)
      /usr/sbin/ifdown eth0
      /usr/sbin/ifup eth0
      ;;
esac

EDIT: have you tried the r8168 driver? That might fix your problem.

@Head_on_a_Stick

I inserted debug line in /etc/rsyslog.conf

#
# __debug__ 7/30/2020 
#
local5.debug			/var/log/debug.log	

#
# Emergencies are sent to everybody logged in.
#
*.emerg				:omusrmsg:*

I created /etc/pm/sleep.d/00fix file.

> more /etc/pm/sleep.d/00fix 
#!/bin/sh
# 
# 00fix: bring network back after resuming from suspend
# 7/30/2020

case "$1" in
     suspend|hibernate)
     logger -p local5.debug "Go into suspend / hibernation"
     ;;
     thaw|resume)
      /usr/sbin/ifdown eth0
      /usr/sbin/ifup eth0
      logger -p local5.debug "Wake up"
      ;;
esac

The weird thing I found was that Xfce's suspend or hibernate would not trigger 00fix file at all. Out of frustration I ran pm-suspend in Xfce terminal, then pm-suspend.log and debug.log were created.

I'm running Xfce 4.12. I suspect that Session Manager (xfce4-session) doesn't properly suspend and hibernate.

Yup, looks like Xfce uses a custom logout command: https://wiki.archlinux.org/index.php/Xfce#Suspend

You could create a wrapper script at /usr/local/bin/xfce-session-logout, something like:

#!/bin/sh
case "$1" in
   --suspend) /usr/sbin/pm-suspend;;
   --hibernate) /usr/sbin/pm-hibernate;;
   *) /usr/bin/xfce-session-logout "$1";;
esac

Re: [Solved] Resume after suspend/hibernation looses eth0 connection

hello,

i am having the same problem.

is there a solution yet?

it happens after coming back from suspend; if i just disconnect the ethernet cable and reconnect, nothing happens, and wicd manager shows no ethernet connection at all.

my ethernet seems this one
