This is caused by a change in the thread-schedule binding. Formerly the
binding didn't correctly set bits 16-19 in the param word to zero as demanded
by the L4 spec. and the kernel now no longer tolerates incorrect parameters.

The bindings have already been fixed in CVS. However, this requires that
you check out the new bindings (l4/pkg/l4sys) and recompile/relink the
programs which used the old bindings.

Please look at the kernel debugger output to see which task inhibits this
behaviour to see which package you need to recompile.

If you have trouble figuring out which task is the culprit, then send in
the last lines of screen output at the time of the stop.

Regards,
-Udo.
