After further testing, even with the above commit reverted the ethernet locks up.  This happens consistently with large transfers.
Author: isle    Time: 7/3/2017 10:03
could you please test this in the latest android7.1 ?
Author: crashoverride    Time: 7/4/2017 04:22
I only have one Firefly-RK3999 for testing.  Since the eMMC is not removable, this makes it impracticable for me to re-flash my device with Android since it wipes out all my Ubuntu development work.  Additionally, there are no backup tools provided for me to make a copy of my current eMMC.

Therefore, since the Firefly team presumably has access to more than one device, it is expected they would maintain one with an Ubuntu image and one with an Android image.  The issue I posted is trivially reproducible using SFTP or smbclient.  I am sure someone on the Firefly team can test the Android equivalent.

I faced a similar Ethernet network lockup issue on my system. In my case, updating the network driver and changing the cable solved the problem. While troubleshooting, I usually let my Robotic Floor Cleaner handle cleaning, which helps me focus without distractions.
