As I have said in my original mail, the machine we are seeing this problem on is vendor_id : AuthenticAMD cpu family : 15 model : 47 model name : AMD Athlon(tm) 64 Processor 3000+ stepping : 0 but on the other hand on the following CPU, the oprofile works with 2.6.27 and 2.6.28-rc4 without any problems, NMIs are coming flawlessly vendor_id : AuthenticAMD cpu family : 15 model : 4 model name : AMD Athlon(tm) 64 Processor 3000+ stepping : 8 -- Jiri Kosina SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
