I think the processor error is normal for a machine with ACPI. I get it on both a new IBM at work and my old Dell Inspiron 4000 laptop at home.

Regarding your problem -- I would look for ways to disable the sound card. It sounds like either a bug in the driver or a hardware conflict. Possibly change the BIOS so that PNP is turned off? Disable sound in BIOS or remove card from computer. There may be a way to disable the sound via a "cheat code" but I don't know of one at the moment.
