I should be asleep when I sent that bug report :)
Well, when using this kernel my ISDN adapter can't connect and  I get some
message in the log like this:
 Sep 22 18:22:23 rcu133 kernel: fsm error: event 20 on state 1 
 Sep 22 18:22:23 rcu133 kernel: fsm error: event 4 on state 1

This messages are printed out in a debug function called
pcbit_fsm_event. This function is not directly called from this file but
I'm almost sure that the only way it could be called from here would be
calling pcbit_l3_receive (which is also on another file).
This one is only called from pcbit_deliver so I think the bug must be
there.

Hope this helps to find the bug. Sorry I took so long to answer but I've
been away for a while.
