I managed to get the 2.6.9-rc3-mm3 and thusly VP-T3 kernel built and running! I had to patch some files: To get mm3 alone working I had to patch a file that VP-T3 patches: http://marc.theaimsgroup.com/?l=linux-kernel&m=109714329614794&w=2 and start the kernel with the i8042.noacpi option. I am patching and building a new kernel that should not need the i8042.noacpi option: http://bugme.osdl.org/attachment.cgi?id=3838&action=view M problem now is that I have ganed NOTHING with respect to latency. This is what I run to do PD, and I still get xruns! sudo jackd -R -d alsa -d hw:1 -r 48000 -p sudo pd my .pdrc: -jack -rt -path /usr/local/lib/pd/externs -path /usr/local/lib/pd/extra -path /home/wade/pd/general -path /home/wade/pd -lib sphere~ -lib fftbin~ -lib zexy -lib Gem -mididev 1,2,3 -r 48000 -sounddev 3 -blocksize 1024 -channels 18 -audiobuf 8 What can I do to lower latency whilst eliminating xruns? When I load a very large patch the whole machine essentially locks up, sputtering and jerking with no response for minuets at a time. Thanks for the continued help with my troublesome x86_64 machine. All I want is a solid machine for performances... -thewade
