[linux-audio-user] Just bought a Delta 1010LT, now what..?

You definitely want to turn off acpi.  I didn't turn USB off since I use
it fro uploading pictures from my camera.  Try moving the 1010LT card
around to see if you can get it on IRQ 9 or 10 by itself.  I have almost
the same setup and I have:

           CPU0
  0:   15340768          XT-PIC  timer
  1:       6854          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  5:          0          XT-PIC  usb-uhci, usb-uhci
  8:          1          XT-PIC  rtc
 10:      33774          XT-PIC  ICE1712
 11:    1858859          XT-PIC  eth0, nvidia
 12:     351739          XT-PIC  PS/2 Mouse
 14:     627800          XT-PIC  ide0
 15:    1548341          XT-PIC  ide1

It took me a few tries to get it to this point.  Note that I don't have
anything on IRQ 9.  I was unable to get it there but since I got IRQ 10
for my card it's OK.
