Try a realtime kernel, setup your irq and jack prios and see if you still get 
XRuns.. If so, it's either a jack backend or audio driver issue (or some jack 
app misbehaves but ardour is rather well behaved ;))..

Anyways, using a latency of 2ms on a non RT system is asking for trouble. You 
don't get scheduling guarantees. Any olde driver can decided to keep the CPU 
to itself for extended times (network drivers are sometimes notorious for 

Try with bigger latency (i'd suggest 1024 frames on a non-RT system, even more 
since you run a 96khz.. maybe 2048)
