Hi,

I have used

ARMBIAN Debian GNU/Linux 8 (jessie) 3.14.79-cubox

the upload speed was horrible about 2,5 Mbytes/s

 

Now I switched the kernel to vanilla

ARMBIAN Debian GNU/Linux 8 (jessie) 4.8.4-cubox

the upload speed is now about 8,5 Mbytes/s

 

On booth kernels the download speed is ok about 48 Mbytes/s

I have also tried to set enable_wait_mode=off without any result

root@tombase:~# cat /proc/cmdline
root=/dev/mmcblk0p1 rootfstype=ext4 rootwait console=ttymxc0,115200 console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 rd.dm=0 rd.luks=0 rd.lvm=0 raid=noautodetect pci=nomsi ahci_imx.hotplug=1 consoleblank=0 vt.global_cursor_default=0 quiet loglevel=3 enable_wait_mode=off

What is the reason for the RX errors/overruns and how can I resolve this?

 

Sincerely
