NSA-320 kirkwood - eth0 link down/up spam in logs (1 reply)

Im using Bodhi's rootfs and kernel updates.
My rootfs is based on Rootfs Debian-3.16.0-kirkwood-tld-2 (sept 2014) I've since updated to Jessie using apt-get and updated kernel to 4.4 and uboot as well.
I'm booting from a USB drive and have a dual drive RAID 1 setup. I'm also quite certain that I wiped out the stock firmware too when I originally set this up back in 2014.

What I'm seeing logged, this has gone on since day 1, and I was hoping that the upgrades that I was doing might have addressed this but it hasn't.


These 3 lines log around every 300 seconds (5 mins), they log in a few places so after some time they cause some rather large log files.

I really don't think the link is actually dropping, as I never see packet loss or a connection drop.
