Does anyone know how to prevent my "nouveau" video card and "ath" wifi |
| 2 |
card from sharing interrupt 19? I can't move the video card slot and |
| 3 |
I'd rather not move the wifi card slot if possible. |

BTW, does anyone see any other opportunity for interrupt optimization |
| 6 |
here? I'm trying to optimize for video and especially audio, and I'm |
| 7 |
using a USB 1.0 sound card. |
