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.

I have a Delta 1010, and rarely run into xruns.
