What's that? We need a kernel patch to make the LAU list work? ;-) Here are the links that Steven posted when -rt14 was released. You might start with these and take a copy of my -rt12 .config file. you'd probably only need to change chipset stuff to get it working: > http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.26.tar.bz2 > http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.26.8.bz2 > http://rt.et.redhat.com/download/patch-2.6.26.8-rt14.bz2 There's also an -rt15 but I didn't see much traffic on that. - Mark _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
