There are some bits missing. Not sure if it is related to your problem or not.
Robert, please take the MIPS preemptible kernel update patch.

O(1) shortens process dispatching time, usually not a big time saver
unless you have *lots* of process and/or you are doing frequent context
switches.
Another patch which is probably more important is the Ingo's breaking
selected big lock patch. That will preemption work more effectively.

You do have to sort them out one by one. (Or you get them all by becoming
mvista customer. :-0)

We'd love to have more people bang on 2.5 MIPS *grin* ...
