Well I did the kernel part, but wasn't sure how you wanted me to disable APIC. I looked in the BIOS but don't see any setting like "APIC On/Off", but there is a few settings for a few IRQ's, and they are set to "Auto". If I go to those options, it shows on one of the IRQ's the network controller and one of the ata controllers, but only gives me the option to change the IRQ for both of them. After doing the kernel and rebooting, I tried again. From what I can tell, there is no change. I untarred a large source file again while playing audio, and about the same result. The mouse also froze several times when the audio was stuttering too, however most of the time I just sat back and listened and watched it untar. I tried to make an audio clip of the stuttering, but for some reason in the clip it doesn't sound half as bad as it did when coming out. I am not sure why, since I took the exact output of the sound card, ran it through a mixer here, and then back in. It should sound equally bad if not worse, but here is a link to the 45 second clip: http://www.tntpowerhost.com/mixx941/samples/SoundCardExample1.ogg I took the last 45 seconds or so of the untar because when recording it, it sounded the worst. However it's not terrible in this clip...the last 10 seconds or so is right when it finished and is playing "normal". -Mark
