Then it's definitely the next exec line that's locking things up.

See if you can do a lot of q <enter> q <enter> q <enter>s during bootup and maybe it'll get you to the shell prompt before it hits that second exec line. If that doesn't work, try Ctrl+C's.

You need to get that second exec line out of your config somehow.

Oh, and that's also the reason why you're not getting a DHCP address for your player by the way. I think the player software has to do DHCP, and it's not even getting that far.
