I created 8 tracks in Ardour 4.7 (downloaded from ardour.org), assigned 
the input to ports 1-8 of the Saffire Pro 40 and recorded for 35 minutes 
with no xruns. Ubuntu 14.04LTS with the kxstudio repo's added in. 
Started jack using QjackCtl with sample rate 48000, frames/period 64, 
and periods/buffer 3. /usr/bin/jackd -u -dfirewire -r48000 -p64 -n3 -I44 
-O44 I normally run frames/period of 1024 and have recorded over an hour 
using eight inputs and no xruns. - Joe
