I'm having no luck getting low latency with a 2.6

I'm using the mm4 patches and have modified the capabilities.h file.
I have this entered into fstab:
shmfs /dev/shm shm defaults 0 0
none /dev/shm tmpfs defaults 0 0
none /tmp/jack tmpfs defaults 0 0
none /mnt/ramfs tmpfs defaults 0 0
and compiled jack with:
./configure --with-default-tmpdir=/mnt/ramfs --enable-capabilities
--enable-realtime
I want to use ardour so that was just a staight ./configure && make
To run jack I go
jackstart -R -v -d alsa -d hw:0 -p 8192
My problem is that I get
**** alsa_pcm: xrun of at least xx.xxx msecs
all the time. I even get it when no audio programs are going.
AFAIK you have got your soundcard set up wrong. I have a SBLive and did
not need any modules apart from the snd_emu10k1 one. I do get a few
xruns when moving windows and switching between apps but that is with -p
512. I am also using the realtime LSM module rather than the hand edit
option but I don't think that is your problem.
What are the alsa bits in your /lib/modules/modprobe.conf (or
/etc/modprobe.conf)?
