The issue appears with 5.6.x and also 5.4.x LTS, now even the DHCP request failed after rebooting with 5.6.11.
As it appears with both kernel branches, I hardly believe it's a kernel issue. But dying ethernet chipsets on a board?
Perhaps the hardware is broken. I don't know. I wouldn't exclude the kernel from being the culprit. It's not related to your issue, but it might be a hardware issue, too, but for rt-patched kernels >= 5.4. My PC doesn't suffer from LAN issues, but while Core/linux-lts and https://aur.archlinux.org/packages/linux-rt-lts/ migrated to 5.4, I stay with 4.19 rt, https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/4.19/ , still LTS, too, https://www.kernel.org/ . $ pacman -Q linux{,-rt{-cornflower,,-securityink,-pussytoes}}|cut -d\ -f2 5.6.11.arch1-1 5.6.10_rt5-1.0 5.6.4_rt3-1.0 4.19.120_rt52-0 4.19.115_rt50-0 I'm doing this because the rt patched kernels >= 5.4 all failed to work with virtualbox and my hardware. Without the rt patch I didn't notice an issue. The 4.19 rt patched kernels don't cause any trouble. Btw. I've got no time for troubleshooting, so I stay with 4.19 for the moment.
