I am running SMP cvs head on the J200 and the K460 and also an A500 recently thanks to the ESIEE team. The K460 has 4 processors which I am hoping will help to identify the SMP problems faster, but it is also exposing new SMP problems for me to look into :( Hopefully we will be able to identify and fix these SMP problems, but they do not appear to be easy and will probably take a while to fix. Thanks for the report! and if you notice anything else odd (or repeatable patterns) let me and/or the list know so maybe it will provide additional insights into the problems.
