Here is the dmesg | pasteinit: http://ix.io/1raX. #1016 plays fine. #1016x does not. 

iperf -c 10.0.1.55 -u -P 1 -i 1 -p 5001 -f G -b 100.0M -t 10 -T 1

Can you test TCP with iperf rather than UDP?

This doesn't look good:

No idea what is causing that at the moment. Unfortunately the log spam has resulted in the log buffer being truncated.

Can you add log_buf_len=16M to your kernel command line, then boot with #1022 (4.18.14, no problems) and run dmesg | pastebinit, then upgrade to #1106 (4.19.1, kernel errors) and again run dmesg | pastebinit, pasting both links here - hopefully this time we'll have complete kernel logs for both a working and non-working kernel. I'll then be able to do some digging. It looks like 4.19 introduced quite a number of r8169-related bugs.

[Milhouse]

@jmerrilljr once more thing that might help: if you can test all of the 4.19-rc test builds (there were 8, rc1-rc8) it might help narrow down the range that includes the breaking commit. You can find links to the 4.19-rc test builds in PR2937. Start with 4.19-rc1 and if that doesn't have the problem then test the next release ie. 4.19-rc2. Post which release of 4.19-rc is the first with the problem. Thanks.

Also, can you describe what your PC is connected to - what type of cable (CAT5, CAT5e etc.), what type of switch (make/model/brand).

 Milhouse, I am running cat6 cable from a Belkin 5D5141-5v4 switch. All my tests have been run on the same 30 gig .mkv file. Other than that I am pretty much lost and overwhelmed. I will try the quoted 4.19 -rc test builds.

I have no idea how to access my kernel command line. Also iperf can't connect to libreelec via TCP. I must be doing something wrong. Thanks for all your help.

[Milhouse]

TCP should be the default for iperf - you're telling it to test UDP by using the -u option. You're also limiting the bandwidth to 100Mb (which you'll probably never see with UDP even without kernel issues).

I'd suggest using the following iperf options on the client:

text:


iperf -c 10.0.1.55 -t 60 -i 10

On the server, you only need:

text:


iperf -s

To access your kernel command line, you need to edit /flash/syslinux.cfg.

To make the /flash partition writeable, you first need to run mount -o remount,rw /flash.

You can use vi or nano to edit /flash/syslinux.cfg.

Make a backup of your current file with:

text:


cp /flash/syslinux.cfg /flash/syslinux.cfg.bak

The kernel command line is the line that begins with APPEND so if your current file looks like:

text:


DEFAULT linux

PROMPT 0



LABEL linux

 KERNEL /KERNEL

 APPEND boot=LABEL=System disk=LABEL=Storage quiet

then you need to change /flash/sylinux.cfg to be:

text:


DEFAULT linux

PROMPT 0



LABEL linux

 KERNEL /KERNEL

 APPEND boot=LABEL=System disk=LABEL=Storage quiet log_buf_len=16M

Obviously, if you get this wrong and corrupt the contents of this file you may have a non-booting system which you can recover using LibreELEC booted from a memory stick (you'll need to boot into live live mode, enable ssh, login with ssh and your internal HDD/SSD will be available via the /media path - restore syslinux.cfg from your syslinux.cfg.bak backup) then reboot from HDD/SSD.

Only make this change if you are confident about making the change.

Yes, and 3.25MBytes/sec over a wired connection is really poor.

Edit: 3.25Mbytes is the congestion window and not relevant. The test results are bogus. I was clearly having a bad day yesterday...

Hmm yeah. The Mac should be running the iperf server, and I assumed the server was 10.0.1.55. The LE client should be running iperf -c ip-address-of-Mac -t 60 -i10.

 No. You host the server on the same computer you cannect to - that only tests Linux's local network which is fast :-)

Hmm yeah. The Mac should be running the iperf server, and I assumed the server was 10.0.1.55. The LE client should be running iperf -c ip-address-of-Mac -t 60 -i10.  

 Brew installed an old version of iperf on my Mac so i need to install iperf3 to be compatible with libre.
