They stick to a certain CPU core for a certain amount of time (sometimes minutes ...) before they are migrated to the proper core and run as expected. Philippe, Gilles, maybe you could generate a new i-pipe patch based on the newest 2.6.37-series kernel. I patched a 2.6.37.6 kernel with adeos- ipipe-2.6.37-x86-2.9-00.patch and the problem was gone. -- Sebastian
