HI TB,
thanks a lot for posting your issue and the solution. I am having exactly
the same problem with a BBBlue, with the 2018-10-07 BeagleBone Blue Flasher

<http://strawsondesign.com/docs/images/BBBL-blank-debian-9.5-iot-armhf-2018-10-07-4gb.img.xz>
from
Strawson Design.
Could you please give me a bit more details on how you disabled the eqep0?
Where did you add the overly that does so?
Many thanks!
Michele
