>2.6.8.1 (pre-empt on -- kernel.org sources compiled via make-kpkg) > drives tuned in kernel config this is no good at all. an unpatched 2.6 kernel is not capable of matching even 2.4+lowlat's performance. its not necessarily true that this is the only source of your problem, but trying to get low latency performance (e.g. in the range of 64-2048 frames/period at 48kHz) out of this kernel isn't going to work even if you fix other issues. Ingo Molnar has patches that appear to make 2.6 almost hard-realtime-safe, a very impressive accomplishment. --p
