I don't mean to hijack this...I'm having the same issue with OpenWRT and VPN router here in Mexico. I boot up the Pi and it hangs on that same br-lan..
IPv6: ADDRCONF (NETDEU_CHANGE): br-lan: link beconcs ready
I have to hit 'enter' but I did not have a USB keyboard, only Bluetooth. Until I found on here, and It's in Spanish!
So I can now get access but it's not "right".
How can I let it completely boot?
Thanks for the help!
