Hi. Yeah, stock 2.4.20 doesn't use ACPI for PCI IRQ routing, which lets
it dodge any issues in this very important area. So, it's hanging at
that spot in your picture?

Can you put printk functions at the top and bottom of
acpi_evaluate_object? This will narrow it down to a hang in the
interpreter, or somewhere else. Also, if you haven't turned on debug
messages, please do so.
