Hello, I am using mainline kernel 4.4 on a QNAP TS-412 (Marvell Kirkwood Feroceon 6281). The network interface mv643xx loses connection after a few minutes to some hours. Only bringing the interface down and up again helps. Now I have a serial console for debugging. When I ping the dead interface and run ?watch ifconfig eth0? on the serial console, I can see the RX packets counting up while TX packets stays unchanged. Log files only show a message of some services showing a timeout or ?if_sendrawpacket: No buffer space available?. How can I figure out what is wrong? Regards, Thomas
