Disappearing Ethernet port
#1
I was stoked to see the release of Armbian-Bionic for Pine A64+ and installed it on a card a couple of days ago. It all runs well except for one problem: when the system boots, the hard-wired Ethernet port doesn't work.

The system sees it as eth0. ethtool even reports "Link detected: yes". But there are no flashing LEDs, and no data actually gets transmitted.

Sometimes when I boot it up, neither of the Ethernet LEDs will light up at all. Sometimes when I boot it up, the left LED will flash once, then nothing. And very rarely, through no pattern I've been able to discern, the system will boot, both lights will flash, and all works beautifully.

I didn't keep an accurate count, but I'd say out of 30 boots yesterday (and by that, I mean I powered it off, then back on again), the Ethernet port only worked about 5 of those times. The rest, it was dead---no lights, but, as I said, the system claimed everything was OK.

I've been running this same Pine with longsleep 3.10.105 without these problems. I've rebooted it three times this morning just to test, and all three times, the Ethernet port was live and worked fine.

Any ideas? Has anyone else seen this issue? I've love to upgrade the kernel I'm running on the Pine, but not if I can't reliably count on the networking.

I have not yet tried Armbian-Stretch.

Thanks!
