I upgraded Ubuntu 17.10 to version 18.04 LTS .... and unfortunately I encountered a problem with the network card / driver: sky2

sky2 ethernet stops working after system resume from suspend !

I returned again from backup to version 17.10 .....

but I checked a few releases of Ubuntu LTS for example Xubuntu 18.04 / Lubuntu 18.04 / mod Voyager LTS 18.04 in LIVE version Everywhere this error occurs:

sky2 ethernet stops working after system resume from suspend !

help trick / script / entry in the terminal:


sleep 5
case $1/$2 in
sudo systemctl restart network-manager.service
modprobe -r sky2
modprobe sky2

chmod +x !


this is probably related to the kernel version on Ubuntu 17.10 is: 4.13.0-39 on version LTS 18.04 kernel 4.15.0-20

  • will there be a patch like kernel or do I need to use this script fix? – kris777 Apr 29 '18 at 11:19

This problem is discussed on the bug reporter at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1758507

According to the thread, a solution should be coming soon. :)


OK ...problem solved I checked dmesg .....error: [ 380.567633] do_IRQ: 3.34 No irq handler for vector

I applied fix to grub file : pci=nomsi,noaer

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi,noaer"

update-grub / reboot and everything works fine ??? :-)

  • or GRUB_CMDLINE_LINUX_DEFAULT="quiet splash sky2.disable_msi=1" – kris777 Sep 10 '19 at 16:45
