1. Please test with a mainline kernel - Ubuntu kernels are supported by Ubuntu only 2. 6.2 isn't a LTS version and therefore won't receive any fixes 3. Re-test with 6.5 or 6.6 4. Disable ASPM L1 and L1 substates via sysfs and re-test -- 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/1874464 Title: NETDEV WATCHDOG: enp5s0 (r8169): transmit queue 0 timed out Status in linux package in Ubuntu: Confirmed Status in linux source package in Focal: Incomplete Status in linux source package in Groovy: Confirmed Bug description: Running focal on a desktop, I accidentally clicked "Enable networking" in nm-applet, disabling my networking. When I clicked it again to reenable it, my networking did not return. After unsuccessfully poking at it for a while, I rebooted and saw the below (and still no networking). `rmmod r8169; modprobe r8169` had no (apparent) effect, nor did further reboots. I rebooted onto two different kernels, both exhibited the same behaviour: 5.4.0-21-generic, 5.4.0-26-generic. I was finally only able to restore networking by _rebooting into Windows_ and then rebooting back into Ubuntu. (My supposition is that NetworkManager/the kernel set *waves hands* something on the network card that persists across boots when it was disabled, and that wasn't correctly unset when I reenabled networking (or on following boots), but Windows _does_ correctly handle that case on boot, and reset it to a working state.)
