As I wrote in the subject line I get an oops with 2.4.0-test13-pre7.

Board: Gigabyte BXD with newest BIOS, Dual processor

Previous kernels ( <=-test12) just printed

ACPI: support found
ACPI: PBLK 0 @ 0x0000:0
ACPI: PBLK 1 @ 0x0000:0
	-0196: *** Error: Sleep State package elements are not both of type
number

Now I get the attached oops.
I've tracked it back into acpi_ns_get_next_object: that function is
called with both child_node and parent_node == NULL, and then the line

	if (parent_node->child)

oopses.

If you need further infos, please ask.
