Again this is architecture problem. I am not sure about Alpha, since I only know about one compiler barrier that is "volatile". What I guess is that in Alpha, it could be something else....maybe it is assembly instruction like "lock" or something. I remember there's an old Linuxjournal article that explains about it. So to avoid further misunderstandings that I might bring, please kindly read this article: http://www.linuxjournal.com/article/8212 Hope that helps... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
