I supposed there is a problem with the compiler, but people there are investigating about problem with cache coherency. You may follow the thread on public web archive, at http://www.linux-mips.org/archives/linux-mips/2008-03/msg00079.html I'll be back on this list after checking any problem with cache coherence and c compiler. Thanks, Giuseppe
