I'll try to decode exact code line.
Uhhuh. It's missing much of the relevant parts of the code line, in
particular the actual oopsing instruction. But what is there decodes
to
41 b8 10 00 00 00 mov $0x10,%r8d
48 c7 c1 88 52 64 81 mov $0xffffffff81645288,%rcx
31 c0 xor %eax,%eax
48 c7 c2 98 52 64 81 mov $0xffffffff81645298,%rdx
bf 00 04 00 0. mov $0x0.00400,%edi
.. oops in here ..
74 33 je 0x50
48 89 df mov %rbx,%rdi
e8 4d c9 00 00 callq ? <offset 0xc972>
48 89 d9 mov %rbx,%rcx
48 c7 c2 0a .. .. .. mov $0x......0a,%rdx
which isn't really very obvious. Do you have that kernel around (or at
least the same compiler and configuration)? Doing a
objdump --disassemble drivers/acpi/acpica/nsaccess.o
I've attached bigger disasfun script output to BZ 51071.
https://bugzilla.kernel.org/show_bug.cgi?id=51071#c1
if (ACPI_GET_DESCRIPTOR_TYPE(prefix_node) !=
00000000000000a1 <acpi_ns_lookup+0xa1> cmpb $0xf,0x8(%rbx)
00000000000000a5 <acpi_ns_lookup+0xa5> je 0da <acpi_ns_lookup+0xda>
seems to be going out of bounds.
