Looking for low latency kernel info on google, btw, yields > outdated information, by and large. search for "realtime preemt" or go directly to https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO To /just build/ a rt kernel you download the vanilla kernel source and the latest rt patch: http://www.kernel.org/pub/linux/kernel/projects/rt/ # tar xfj linux-2.6.33.7.tar.bz2 # mv -vi linux-2.6.33.7 linux-2.6.33.7.2-rt30 # cd linux-2.6.33.7.2-rt30 # bzcat ../patch-2.6.33.7.2-rt30.bz2 | patch -p1 # make config # :) # make-kpkg --rootcmd fakeroot kernel_image configuring the kernel is the hardest part.. :-) After installing you'll also want to do some additional setup: eg install Rui's rtirq script and tweak limits.conf As for "stock" options: This issue has recently been discussed on this list: see the thread " rt kernel in debian/squeeze" http://lists.linuxaudio.org/pipermail/linux-audio-user/2011-January/thread.html http://wiki.linuxaudio.org/wiki/real_time_info has lots of links and list of audio-distributions.
