I always compile my software, so the first time I notice it was after upgrading to 3.7.0 kernel. Anyway I'm not sure if it appeared after the upgrade to 3.7.0 kernel. But ok. If I have some more of these issues, I will report here. Thanks for the great support! -- Linux 3.7.0: Terrified Chipmunk http://www.youtube.com/DanielFragaBR http://www.libertarios.org.br
