sometimes, when booting up/resuming from disk, I get an oops[1].

obj_desc->common_field.access_bit_width is zero, but even after the

Would please try below debug patch to see which region filed is
accessed?

I'm confused, but keep trying.

Got it again. obj_desc->common_field.node is martian too (0x4000000), so the added acpi_get_name dies:

Whole common_field seems to be mangled. Ideas?
