the driver has unholy private knowledge of its great-*cgrandchildren. The ACPI allocation routine lacked such knowledge when it tried to do a default allocation for all descendants, rather than just its immeidate children, so would access grandchild's ivar in an unsafe way. This could lead to a panic when devices were present which had no addresses setup by the BIOS, but which were later allocated in a lazy manner via pci_alloc_map. As such, only do the default allocation adjustments for immediate children. The manner that acpi_sysres_find accesses the resource list, used later in acpi_alloc_resource, is safe and proper so no additional test is needed there. This fixes a panic when probing an disabled ata controller on some newer intel blades. Reported by: dwhite |
