Same problem with the x86_64 build on an Intel NUC.
The bluetoothd daemon crashes when starting. I fixed that by running bluetoothd in debug mode (don't know why it works that way, just found that by testing to understand why it crashed), but then associating bluetooth controllers still fails, and sometimes crashes emulation station (which explains the black screen).
By the way, is there a better way to report issues than this forum ? I didn't see the issues tab in github (it's more easy to find an existing reported bug in github than in a forum).
