If I disable every= thing, there is no hum. If I re-enable coldplug (COLDPLUG=3D"yes"= ), then the hum re-appear.

What about coldplug could be causing prob= lems? Where should I go from here to solve this problem?

What exactly i= s happening at the "Unpacking firmware" stage of the boot process= ?
Is there a way to find out exactly what firmware is being loaded? Or a way = to boot without loading the firmware?

Why? It is a somewhat strange reason. I am having issues with a high-pitched hum coming from the audio jacks (occurs on both MB sound and a creative sound card)
I have a very nice sound system (a sound board, studio monitors...I am=20 an audio hobbyist), and no other system has these problems, so I am=20 relatively sure that it is not the speakers/cables.

I have been=20 booting from the liveCD, and I have pinpointed the point at which the=20 hum starts to something near the *Unpacking firmware stage.
I realize this is somewhat esoteric, but it renders my system almost useles= s, and would greatly appreciate any input.

I did inte= ractive mode. The interactive mode only prompts for some of the items. Among the items it does not prompt for is the firmware unpacking. It=20 just goes and does it.
