09:01 <sheepman> hi all, got a strange problem with my S912 SoC. Any armbian build I try that uses kernel v3 ethernet works fine, but with any that uses kernel v4 the ethernet stalls under high load (it has gigabit ethernet btw). Any clues or help?

09:08 <sheepman> RTL8211F chipset btw

10:44 <sheepman> feels like it's related to amlogic,tx-delay-ns but a value on 0,2,4,6 doesn't fix it. In fact anything above 2 makes it worse.

10:52 <sheepman> also although the documentation says only values 0,2,4,6 are valid it seems to accept others too

10:52 <sheepman> but i can't find anything that fixes it, improves it a little but not fixes it

10:53 <sheepman> under load tx just dies, I kill it quickly by just running iperf3 -s then firing some packets at it. Takes between 1-7 seconds to die depending on what tx-delay-ns value i use so far

12:43 <narmstrong> @sheepman: you need to disable eee like on odroid-c2

12:44 <sheepman> @narmstrong: ok, how do i do that? any points?

12:44 <sheepman> *pointers

12:48 <narmstrong> Look at the odroidc2 dts

13:19 <sheepman> @narmstrong ok thanks

13:41 <sheepman> @narmstrong: doesn't appear to of made any difference unless I'm doing it wrong

13:54 <sheepman> ahhh although disabling it with ethtool solves the problem! thanks @narmstrong ! my hero :

13:54 <sheepman> :)
