Eventually it crashes hard, after probing hde. Looking at your dmesg dump from 2.5.75, another problem is here, where it tries to route lots of your PCI IRQs to IRQ 0. It seems to be failing to program the IRQs. No idea why yet. BTW: is there a way to get more detailed debug output on ACPI? There are loads more debugging print statements in the code than are appearing in your dmesg (or in mine as well) even with ACPI Debug statements turned on. pci_link-0256 [21] acpi_pci_link_get_curr: No IRQ resource found ACPI: PCI Interrupt Link [ALKA] enabled at IRQ 0 pci_link-0256 [22] acpi_pci_link_get_curr: No IRQ resource found ACPI: PCI Interrupt Link [ALKB] enabled at IRQ 0 pci_link-0256 [23] acpi_pci_link_get_curr: No IRQ resource found ACPI: PCI Interrupt Link [ALKC] enabled at IRQ 0 pci_link-0256 [24] acpi_pci_link_get_curr: No IRQ resource found ACPI: PCI Interrupt Link [ALKD] enabled at IRQ 0 ------------------------------------------------------- This SF.Net email sponsored by: Parasoft Error proof Web apps, automate testing & more.
