Fine - I'm just offering the parts that I recall working around it for me - if you are unwilling to at least try it, maybe someone else can and report back so we know if it is or isn't related. >>Also, have you tried disabling apic? > > > I think you mean ACPI. This machine doesn't have an APIC. No, I meant apic.

I also had problems with it. I ended up replacing it with a mini-pci atheros card.
