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.
