I am currently using 2.6.16-gentoo-r2 with no low latency patches. It works fine on my AMD64 hardware, at least for low work load low latency needs. I run at 64/2 on my HDSP 9652 and get no xruns doing mostly mixing and a very little recording. However I do require realtime-lsm be enabled and loaded. Without realtime-lsm all kernels on my machine, with or without Ingo's patches, cause xruns. I have not tried the pam enabled realtime methods as there doesn't seem to be any value spending the time to do it just yet. Cheers, Mark
in 64 bit? What mobo? I've given up on ingo's patches on my 64 bit machine here.
