Have others used oprofile successfully on amd64? I have two dual-core systems, one AMD x2 and one Intel (Core2 Duo). Neither of them collects any samples. My Pentium-M (i386) system works fine with the current packages, although that's using timer mode rather than the NMI interrupt. thanks Hamish -- Hamish Moffatt VK3SB <hamish@debian.org> <hamish@cloud.net.au>
