Not long ago, I learned that IRQ 9 is commonly used by ACPI. I've got
several machines which won't boot certain kernel versions (and this problem
seems to "come and go" as the versions progress).
Booting with "acpi=off" makes them all work. I have no idea why. You may
also want to fiddle with any BIOS settings to enable/disable ACPI.

It's not that hard. No matter what the problem is, tell the customer
to reinstall Windows.
