As a followup to the last post, I was trying to compile a new kernel. I used make -j3 to speed up the process, after all, the Banana Pi has a dualcore CPU, so 3 threads should be appropriate.
But whenever I start that, it seems to hang and not do anything, so I decided to hook it up to HDMI and give it a try there. It is currently compiling, but as it is 2:20am, I will most likely post results of that in the morning, if not when returning from my day job.
Solution: cross-compile on another CPU, that does not take ages as well.
