I think much (most? all?) of the lowlatency patch set was merged into the 2.6.1 release. I'm not entirely sure of that now, looking through the changelog -- but, there seem to be a number of things mentioning lock-break patches or fixes to general locking type stuff. If I understand correctly the lowlatency patches were/are mainly about breaking up locks that the kernel sometimes holds too long. (I don't really know what any of that means ... :-\ ) I think the -mm tree has become the official testing/holding ground (for now at least) for patches between releases of the 2.6.x series As far as annectdotal evidence, I'm running jack and ecasound right now with jack started this way: jackstart -v -R -d alsa -d ice1712 -r 44100 -p 128 -n 2 using linux 2.6.2 and alsa-drivers-1.0.2c. Seems to be working fairly well here. no dropouts or xruns while browsing, writing this mail, switching desktops, or switching out of X to the console. -Eric Rz.
