[linux-audio-user] Please help me tune Jack (with Freebob, improving on the ASork distribution)

Hi there!

My first big success since I bought my BeBoB based audio interface: It
works! :)

I used the beautiful little audio distribution called ASork by Johan
Mattson, which really embodies everything I could ever expect from a
linux audio distribution. I expanded its use to Freebob and I will be
feeding my experience back to Johan, so expect a perfectly usable live
cd with the option of Debian installation with the power of Freebob!

I am working to get the thing absolutely, rock solid stable to the point
you can use your consumer-end PC as a live instrument and I will be
testing it on road conditions. As of now, every few minutes or so, I
experience a one-second XRun. I would like to invite anyone with
expertise in eliminating XRuns and increasing Jack's performance to
reply with measures I could take.

Here are the exact circumstances:

* ASork is a Morphix based LiveCD with realtimed kernel
* I am using version 0.04, with the kernel of 0.02, due
  to a bug that causes a hard lockup (mouse pointer won't
  move, must hard reset system) when starting Jack with the
  Freebob backend. That is kernel 2.6.15 with the realtime
  patch; at this time it is unknown to me whether Johan
  applied other patches or whether they might be relevant.
* ASork 0.04 is installed to disk, and expanded which
  packages from the Debian Sid repository, along with the
  FreeBob and Freebobified Jack packages from Debian Experimental.
* there is a line 'none tmpfs /tmp/jack defaults 0 0' in /etc/fstab

What can I do to make my system absolutely foolproof realtime?

Thank you.

Carlo
