------- Comment #13 from [EMAIL PROTECTED] 2008-04-25 03:51 -------
Ok, I played around a bit with driver/acpi/video.c and put in printk's. This is
the result I got:
[ 848.382135] ACPI: Entering acpi_video_init
[ 848.382216] ACPI: Entering acpi_video_bus_add
[ 848.382265] ACPI: Entering acpi_video_bus_find_cap
[ 848.382322] ACPI: Entering acpi_video_bus_check
[ 848.382373] ACPI: Entering acpi_video_bus_add_fs
[ 848.382426] ACPI: Entering acpi_video_bus_get_devices
[ 848.382478] ACPI: Entering acpi_video_device_enumerate
[ 848.382528] ACPI: Calling acpi_evaluate_object
So the code leading up to the crash is:
static int acpi_video_device_enumerate(struct acpi_video_bus *video)
{
printk(KERN_ERR PREFIX "Entering %s\n", __FUNCTION__);
int status;
int count;
int i;
struct acpi_video_enumerated_device *active_device_list;
struct acpi_buffer buffer = { ACPI_ALLOCATE_BUFFER, NULL };
union acpi_object *dod = NULL;
union acpi_object *obj;
printk(KERN_ERR PREFIX "Calling acpi_evaluate_object\n");
status = acpi_evaluate_object(video->device->handle, "_DOD", NULL,
&buffer);
And it seems to crash in the acpi_evaluate_object function.
I'll see if I can get more info.
Let me know if I should test something specific.
