Public bug reported: Hello, After a long time in sleep mode, my Desktop running Ubuntu 20.04 loses its network ethernet link. the demsg shows the following lines after sleep exit:
[10402.613687] PM: suspend exit [10403.035311] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) [10403.121362] ata1.00: configured for UDMA/133 [10403.363882] e1000e: enp0s25 NIC Link is Down [10406.484276] e1000e: enp0s25 NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx [10406.484281] e1000e 0000:00:19.0 enp0s25: 10/100 speed: disabling TSO [10406.484322] IPv6: ADDRCONF(NETDEV_CHANGE): enp0s25: link becomes ready the ethernet is up but at 10 M / full duplex DHCP of my router does not give any address. the only way to retrieve a Full 1000 M functionnal link is to reboot the machine. Can't determine how much time of sleep it needs to reproduce, since an immediate sleep/wake-up does not produce network loss. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: network ** Attachment added: "lspci-vnvn.log" https://bugs.launchpad.net/bugs/1872408/+attachment/5353029/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872408 Title: Network lost after long sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872408/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
