Comment 1 Thorsten Leemhuis 2017-03-27 09:53:25 UTC
Lo Awjb. Long time no see ;-) 

Does this problem happen on older versions (<= 4.10) already, or is this something that new with 4.11-rc? In the latter case it might qualify as regression.
Comment 2 Andreas Bierfert 2017-03-28 12:48:31 UTC
Hi :)

I did not see this on the specialized pine trees (based on 4.9). I will Try to dig a bit deeper...
Comment 3 Stefan Brüns 2017-04-04 08:29:40 UTC
Tried the following variants:

4.9.x plus Pine64 ethernet/usb patches
4.10.x plus ethernet patches
4.11.0-rc4 almost vanilla
4.11.0-rc3 plus ethernet patches

4.9.x and 4.10.x are fine, both 4.11.0-rc are not, so its likely a 4.11.0-rc regression
