I cannot reproduce that. I just tried to connect from my Dual PPro, which 
is still running 2.4.21-pre4 with no updates to BT stuff, to my laptop
with very latest bt-2.4. 
I get normal trace

(first UIH sent before last MSC response came from 2.4.21-pre4 
which doesn't have MSC fixes).

So. I'm absolutely sure that new code is 100% compatible with the old one. I see
no delays in SABM processing.
And I have no idea what's going on with your P4 :).
