Pedro, Thanks. Yes, the machine is a dual-CPU machine. I will search the bug now, if it is still not fixed in the updated kernel, I will build a vanilla kernel then. Thanks. --Guolin Cheng -----Original Message----- From: Pedro Fernandes Macedo [mailto:webmaster@xxxxxxxxxxxxxxxxxxx] If I read correctly , this machine is a dual CPU , isnt it? Try compiling a vanilla kernel and see if crashes.. if it doesnt , it means that you've hit a known bug... I dont have the bug number here , but if you search the archives for "SMP stability" you may find them... The kernel developers are working on it already ... -- Pedro Macedo -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: http://www.redhat.com/mailman/listinfo/fedora-list
