Can't start L4Linux-2.6.18

In august, I tested L4Linux on PC, and everything was working fine with L4Linux-2.6.17.
Now, I get the snapshots of 20061116, and rebuild everything.
The L4Linux kernel is now 2.6.18.
The build is ok, but I can't start it under Fiasco.

Here is the log :

Of course, I have the exception_ipc feature enabled in Fiasco !!!

If I rebuild L4Linux-2.6.17, with the L4Env from 20061116, and try to start it under Fiasco, there is no problem ...
