I just bit the bullet and decided to have a go at rolling my own kernel for 
the first time, following the DeMuDi HOWTO 
http://demudi.agnula.org/wiki/Low-latencyKernelBuildingHowto and a certain 
amount of advice from Antonio and well, 5 builds later I seem to have a 
working kernel! I´m using the patched libpam modules from Ubuntu (heh ;) with 
2.6.16.5 so far so good. Ardour-0.99 seems happy, with a really low dsp. 
Certainly as good as I´ve had with earlier -rt patched kernel packages from 
DeMuDi.

I´m wondering whether setting negative nice values 
in /etc/security/limits.conf is necessary or even a good idea. I shall have 
to play around and fine-tune things a bit yet.

Now I have started I may as well build an -rt patched version to test the 
difference. Does it conflict with PAM rtlimits?
