(see http://www.ussg.iu.edu/hypermail/linux/kernel/0307.2/0713.html ) (kernel-2.6.0-test4) The kernel crash in resource/nsutils.c line 740 : if (ACPI_GET_DESCRIPTOR_TYPE (handle) != ACPI_DESC_TYPE_NAMED) { because handle == 7 and #define ACPI_GET_DESCRIPTOR_TYPE(d) (((union acpi_descriptor *)(void *)(d))->descriptor_id) this value is set in resource/rsmisc.c line 95 function acpi_rs_end_tag_resource: output_struct->id = ACPI_RSTYPE_END_TAG; in resource/rslist.c function acpi_rs_byte_stream_to_list output_buffer (= output_struct) is changed to the same value than handle Since I don't see how to fix the code, I have this ugly workaround : in pci_root.c line 294: handle = device->handle; acpi_pci_evaluate_crs(root); device->handle = handle; handle = NULL; -- Cedric Hans ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
