Hi LAU,
Right now, I'm optimizing my system for audio work, and have experienced some
problems.
First, this is my system: Kubuntu 9.04 with 2.6.28-3-rt (noacpi nosmp (the
system freezes w/o nosmp, possible because of the nvidia x-driver)), jack
1.9.2 running on an Athlon64 X2 6400+, 3.2 GHz with 8 GB RAM and a MSI K9N SLI
Platinum MB. The Soundcard is a Delta 1010 from M-Audio. All in all, a decent
Audio HW I believe.
...
I had much more success by adding the 64Studio repos and using the 2.6.29 kernel - and
most other stuff, actually - from hardy-backports. I've tried the ubuntu -rt kernels
from both Intrepid and Jaunty 32 and 64bit and they were horrible - system lock-ups, apps
crashing, sync problems, MIDI problems, zombied apps, irq problems, no smp, etc, etc,
etc.
Yoy will need to compile your own NVIDIA drivers (takes 5 minutes to compile and install).
You should be able to run with smp and acpi again. :)
