xruns when logging in to fluxbox

I am reposting this message I posted to demudi list in hopes
that someone here 
can make heads or tails of it.

My first question is: It there a way to check if realtime is
really working?

I am running demudi 1.3 with what others have confirmed is
totally adequate 
hardware. When I first boot demudi I can start jack with the
following 
command:

/usr/bin/jackd -v --realtime -u -dalsa -dhw:0 -r96000 -p256
-n2

I would like 96000 in order to create high quality DVD
audio. 

But when I login to fluxbox and qjackctl, gkrellm and other
apps start I see 
output in qjackctl's display like this 1(4532) after about
30 seconds. I then 
go back to the command line and I willsee the following
repeating on the 
command line very fast:

delay of 2810.000 usecs exceeds estimated spare time of
2664.000; restart ...
delay of 2810.000 usecs exceeds estimated spare time of
2664.000; restart ...
delay of 2810.000 usecs exceeds estimated spare time of
2664.000; restart ...
delay of 2810.000 usecs exceeds estimated spare time of
2664.000; restart ...
delay of 2810.000 usecs exceeds estimated spare time of
2664.000; restart ...
delay of 2810.000 usecs exceeds estimated spare time of
2664.000; restart ...

and on and on......

After this I cannot get jack to respond properly unless I
kill all apps 
running in fluxbox and don't pull up the menu in fluxbox.
Even simple mouse 
commands to view the fluxbox menu cause xruns!

- I have used Ingo Molnar’s 2.6 kernel patch (I am having
the same problems in 
the default 2.6 kernel with demudi 1.3 with kernel 2.6 and
do not remember 
these problems with demudi 1.2.1 kernel 2.4)
- I have set my Audio Card priority to 99 (also tried as
default)
- I have set my jack priority to 70 (toggled between 0 and
70)
- I have installed and configure realtime-lsm (played with
all parameters)
- I have put export LD_ASSUME_KERNEL=2.4.19 in my
/etc/profile

What else can one do to solve this problem? I am stumped!

Thanks
