Hi Loki,
I'm running exactly that kernel in 64-bit mode:
mark@lightning ~ $ uname -a
Linux lightning 2.6.15-rt2 #2 PREEMPT Thu Jan 5 16:13:25 PST 2006
x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
mark@lightning ~ $
It works OK for me. I'm xrun free at 64/2 on my HDSP 9652 for anywhere
from 2 - 6 hours and then I'll get a flurry of xruns. I see pretty
much the same problems in Aqualung, which doesn't generally mind the
xruns, or Ardour which will usually shut down when they happen. Folks
here have blamed my complicated setup which uses the Gentoo chroot'ed
32-bit environment for web browsing and 32-bit multimedia only, but
I've run the same tests with all of that turned off and still see that
problem.
I see no issues like you are describing with CPU usage, but I'm using
an NForce4 chipset with an ATI PCI Express video card. Possibly it's
an ATI chipset issue.
I could send you a copy of my config file offline.
Cheers,
Mark

Has anyone actually got this working? If so how and
with what
settings? I've got 2.6.15 with patch-2.6.15-rt2 to compile fine and
boot but the irq handlers seem to use 90% of cpu and the system really
feels like it's chugging, everything takes 10 to 100 times longer to
load, and anything musical is impossible. I'm running amd64 3000 on an
ati chipset based mb. All normal modules, nothing external. I've tried
with a number of older kernels / patches but i'm wondering if there is
a magic collection that actually works. ;-)
