Same issue here.
I am using Orange pi one.
Problem afer installing 6.6.16-current-sunxi
Huge utylization of CPU / system freze, I also using, mjpg_streamer, I am metionig about this, because I can only make it working/unfreze only after getting feed from camera on that hardware. I know weird, but it is how it is.
