Thank you for the config. I'll try building on that.
I see you have the security capabilities on. Do you use the realtime module
I was talking about? Or do you use the capability/commoncap in a special
way? Are there some module parameters I should give to capability or commoncap?

My kernel config is attached. I don't have
problems with latency. I'm
not using any apps with GUIs, though. So you probably have more
variables in the mix than I do.
I'm using ecasound w/jackd and a delta66.

I'm trying to get jack & ardour working
with the
2.6.x kernels. Do you
have any hints/tips? I've now tried:
debian 2.6.2
debian 2.6.3
debian 2.6.3 modified with LSM support + realtime
module
standard 2.6.4-rc2-mm1 (couldn't get realtime
module working)
standard 2.6.3-mm4 LSM support + realtime module
(kinda working..)
None of these have provided me with sufficient
latency. Jack keeps
throwing Ardour out for stupid reasons like closing
the mixer window.
(with realtime module, I mean
http://www.joq.us/realtime/)
Is there some magic trick I've forgotten to do, or I
haven't heard of? I
have DMA enabled on my harddrive, and this same
system runs like dream
with 2.4 kernels.
Thanks
Sampo
No I have the same problem. I have asked anyone who
has it running satisfactorily to post their kernel
config here but no-one has so I assume that a lot of
people have the same problem

I'm using the realtime lsm by jack o'quin/torbenh. I load it in
/etc/init.d/bootmisc.sh like this:
insmod /usr/src/realtime-0.0.3/realtime.ko allcaps=1 gid=29
I build it, but don't run the make install since doing so wipes out all
other modules. That's why I use insmod instead of a modprobe. (I'm open
to suggestions on better ways if they exist.)

There's nothing wrong with this.

What happens when you run `make install'?
If you have KERNEL_DIR set correctly, it *should* reinstall all the
modules configured for your kernel sources. To save time, I usually
do the kernel `make modules' but no `make modules_install'. Then, the
realtime `make install' will install everything once.
If we can figure out what's going wrong, I should at least make the
INSTALL instructions clearer.

Ah! No hurry. I wouldn't expect that to work, anyway.
Some of the Debian multimedia folks are talking about packaging and
distributing it. So, that may become a lot easier, eventually.

If you're going to build with 2.6.4, you'll need the newest version,
realtime-0.0.4. Linus recently changed the way concurrent groups are
stored in the task structure (actually, they're not in the task
structure anymore). I'm building 2.6.4 to test with it as we speak.
My thanks to Martin Habets for pointing out what needed to be done.
This version *should* work either way, it's in the usual place...

I have 2.6.4 working with the realtime-0.0.4 module. I didn't have time
to investigate getting it to fit into a debian kernel package, so I just
made it separately again and continue to insmod it from
/etc/init.d/bootmisc.sh.
I did take a quick look at the make-kpkg man page. The --added-modules
foo option might be of interest. I think it's meant to build modules
from source directories outside the kernel tree and perhaps include them
in the kernel deb package(?). But, I didn't have chance to play with it.
