Good guess, Michael, but probably incorrect.

I've been through this.  It's a weird issue between VIA mobos and 
certain drives.  Replacing the drive with a different make/model _might_ 
fix the problem.  I have a maxtor 80 GB that has the problem, but the 
second IBM drive in that system does not.  The drive with the problem 
_never_ has the problem on my nforce mobo.

The disable apic support suggestion is likely the correct answer.  You 
have two options, either recompile your kernel removing the "local APIC 
support" or disable it at boot with your boot manager.

I googled this and found many different options suggested for boot time 
to disable APIC, so I just put them all into my line and these problems 
went away.

in lilo.conf look for the kernel you are booting and make sure the 
following entries are in your "append" line:

noapic nolapic pci=noacpi acpi=off

Oh, and do as I do - don't buy another mobo with VIA chipsets to run 
Linux on. ;-)
