I use the repo RT kernel without patches but , but almost all the other music

My use of waf does probably do the same as you suggested, here is my
configure recipe:
PREFIX=/usr ./waf configure
./waf build
sudo ./waf install.
This way, 1.9 will replace your current jack installation. Some programs might
probably complain because 1.9 do have a slightly different API, but my Ardour
2.7.1, Rosegarden 1.7.2, CVS version of the Linuxsampler apps and all
important LV2 and LADSPA plugins works just fine, so I'm happy.

... I have no more xruns (using 2.6.27-3-rt on
8.10 with KDE 4.2
desktop) and the latency I use when recording is normally 1.45 ms on
my lap top with acpi off. The USB card is an old M-audio Mobile PreUSB
(44100 16-bit). I do not record often with on my lap top, but
everything works fine when I have to use it.
So you might give the 2.6.27-3-rt the last chance with some help from
jackdmp 1.9 (the upcoming jack 2.0). I have used jackdmp around 11
months now and it's IMO the only choice on a 64 bits machine with more
than one core. I also use jackdmp on my studio machine and are really
happy with it.
I hope this helps.
Hi Jostein,
This is interesting. Did you patch the rt sources at all or are you
running the kernel as it came from the repo ? Did you simply drop-in the
jackdmp version of jackd (./waf configure --prefix=/usr) or was any
other action required ?
