The ACPI unknown exception in Bjorn> the acpi_motherboard_init() path is understood and being resolved. Ok, let me know when you've got a proposed patch and I'd be happy to test it out for you. I thought it might be related since it mentions IRQs and my timeout problem was/is IRQ related possibly. Bjorn> Your boot hang/IRQ problem is something completely different. Yeah, it looks to be a problem with the new ata/hpt366 driver not setting up my HPT302 Rev 1 chipset properly on a PCI card.
