KDB has been superseded by JDB. JDB is in fact the Fiasco kernel debugger.

When entering the kernel debugger, you should get a line similar to this:

---------------------------------------------------ESP:201807a8 EIP:00006526
(6.00) jdb:

6.00 in this case is the thread that was active, when the debugger was
entered (thread 0 of task 6). When the "fix your bindings" message appears,
then note the task number (number before the dot). Compare it to the task
numbers that "rmgr" or "loader" report when starting tasks, i.e.

RMGR: loading "pingpong-ux"
      from 01d37000-01d6f72d to [ 00800000-0080f1c3 00810000-00960580 ]
      task #0x06 at entry 00800000 via trampoline page code 00070150
      ^^^^^^^^^^ Task 6 is pingpong-ux

or

loader  | vmlinuz.l4env,#f: Continue at l4env_init (00013350, libloader.s.so)
          ^^^^^^^^^^^^^^^^  Task 0x0f is L4Linux

And voila, you'll find the offending program that needs fixing.

Could well be. Only the task number will tell you for sure. Remote-CVS has
been updated recently (Friday, Sep 5), so all the fixed bindings should 
have propagated to the wide world.

You don't need to re-checkout packages. A simple "cvs update -dP" in any
of your checked out directories will bring it up-to-date. Of course you
still need to recompile the relevant packages afterwards.
