kernel 5.4 - r8168 vs r8169 - ethernet

Hi guys

Ever since I got kernel 5.4 I got random ethernet disconnections and lower overall speed with r8169 (uninstalled r8168).

I finally removed kernel 5.4 - running now 4.19 - and have noticed no problem with r8169.

Does anyone have this problem too?

What do i do?
Should I just keep kernel 4.19 for as long as it is supported?
Should I try kernel 5.4 with r8168? Is that even possible?


# inxi -SN
System:    Host: {removed} Kernel: 4.19.91-1-MANJARO x86_64 bits: 64 Desktop: Xfce 4.14.1 Distro: Manjaro Linux
Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169

It's not the driver, ethernet networking on the 5.4 kernel has been problematic for many, just do a search. I can't use the 5.4 kernel on my system either, the whole system slows to a crawl, and seems frozen for hours. If it wasn't for the fact that I can tell it's not frozen as things I initiated fifteen minutes, to an hour earlier, finally happen. It's almost like a really bad memory leak, that i'm running out of system resources, or that the processor is over taxed.

Which is strange since I have a pretty beefy system:

I had no issues before, or after going back to the 4.19.x kernel.

Thank you very much for the reply.
I had found 5.4 ethernet issues posts but I thought they were somehow resolved in the meantime.
And to think that 5.4 is supposed to be a LTS kernel!

A: Upstream still has 5.4 marked as stable, it won't be an LTS until 5.5 moves into the stable branch.
B: Just because the releases tab has a kernel scheduled to become an LTS, does not mean it will.
C: Even if it was, what does that matter?
I have one system here that has various issues with every kernel past 4.9, and another one with stability issues on anything past 3.16.
