That message is for L2CAP channel used for SDP. Don't worry about that.

I also had similar problems.

Here is my /etc/ppp/options.ttyBT0 on the server side:
    noauth nodeflate nobsdcom plock
    mtu 256
    debug
    local
    silent
    10.0.0.1:10.0.0.2

/etc/ppp/options.ttyBT0 on the client side:
    noauth nodeflate nobsdcom plock
    mtu 256
    debug
    local

As a general recommendation I'd suggest to disable most of pppd 
features(compres, etc)
and modem emulation for now.

I've modified btd to start pppd with just 'pppd /dev/ttyBTx' to use options 
from /etc/ppp/options.ttyBT0.

I run btd as:
     btd -u /dev/ttyS0 -s 57600 -m -e 0

That works pretty reliably for me.

Also I've seen bunch of SDP crashes so it is disable for now and RFCOMM 
uses hard coded channel 1.

All the best
Max
