What are the hardware specs of your desktop and what soundcard/midi
controller are you using? Do you have any extra boot options in your
menu.lst (eg. noacpi or some such)?

You mentioned that you had 64Studio installed, does it fare any better
with your hardware? I have 64Studio on my Desktop and Ubuntu for my
laptop and am familiar (and happy) with both distros.

I'm going to suggest a clean reinstall of Ubuntu Studio-Hardy on the box
in question *if* you really wanna see if it's the HW or your
configuration. Feisty->Gutsy->Hardy. Many things could have happened
over this time frame.
