I'm trying to recompile the image from source (because I want the kernel with SATA PMP support, and I got the SATA port multiplier and 3 drives ready), but failed in the last step. As the attached image, the problem should be caused by "Device or resource busy".
I'm using a fresh downloaded Ubuntu 16.4 VB image and follow every instructions in github.
So, how can I get rid of it? Am I missing something? Thanks.
