Hey there, I'm having this issue with a Mint 19 (bionic) installation and two Marvell 88E8053 NICs. Logged in, press the power button or the Suspend menu, computer goes to sleep. When awoken from the power button, "Network cable is disconnected".
I found the workaround of "sudo modprobe -r sky2; modprobe -i sky2" to work quite nicely. $ uname -rms Linux 4.15.0-47-generic x86_64 Tested with: * linux-image-4.15.0-47-generic/bionic-updates,bionic-security,now 4.15.0-47.50 amd64 * linux-image-4.18.0-17-generic/bionic-updates,bionic-security,now 4.18.0-17.18~18.04.1 amd64 If you need any more details, please feel free to be as analytical as possible ;) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1798921 Title: sky2 ethernet card don't work after returning from suspension Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Status in linux source package in Bionic: Confirmed Status in linux source package in Cosmic: Confirmed Bug description: Bug very similar to #1752772 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752772) but affecting the sky2 driver instead of r8169. After system suspend the ethernet connection stops working. The card is still up and the modem can see it is connected, but the card doesn't get an ip address. Ifconfig down/up and restarting network- manager does not solve the issue. Similarly to the other bug, "sudo modprobe sky2 -r" an then "sudo modprobe sky2" solves the issue.
