Howdy,
With old kernel (from 3.10 to 3.14-rc1), my hp box shows following
outputs:

However the box can boot up and works well.
After I update kernel to 3.14-rc2, it panic when booting. Here is
console output:

OK, this looks like a bogus BGRT address, that's a 64-bit physical
address. I suspect the BGRT address is actually 0x1376e018, but that's
just a guess. This looks like a BIOS bug.

Well, nuts. I think this is my bad. Does reverting commit 081cd62a010f
("x86/efi: Allow mapping BGRT on x86-32") make things work? Or at least,
work as well as they did prior to -rc2?
I wonder if we're calling early_memremap() when the fixmap slots are no
longer valid. Could you try building the 'urgent' branch at,

Sure.
Yes, after revert 081cd62a it can boot up. (Of cause the ioremap failed
as before.)

Thinking about this a bit harder that PTE is invalid because bits 52-63
are not zero, which is exactly the problem you were hitting prior to
-rc2, namely that the physical BGRT address is bogus.
Can you post the EFI memory map entries from a dmesg? I just want to
make sure that it really is the BGRT address that is broken and not
something else. Also, please post the ACPI: BGRT entry from your dmesg
too. Thanks.

Your BGRT table has an extra 4 bytes for some reason, (0x3C should be
0x38) and doesn't match the defintion in include/acpi/actbl3.h,
struct acpi_table_bgrt {
struct acpi_table_header header; /* Common ACPI table header */
u16 version;
u8 status;
u8 image_type;
u64 image_address;
u32 image_offset_x;
u32 image_offset_y;
};
which explains why when we dereference ->image_address we don't get a
sensible value.
Guys, what do you make of this? Firmware bug? Full thread here,

Firmware bug, but I guess we'll need to work around it.

Hi Matt,
Yes, I agree that the table size should be 0x38. However, ACPI spec
states that bit0 of status indicates if the boot image graphic is valid.
This bit is set to 0 (invalid) on the system. Can you check this bit
and return when invalid?
Thanks,
-Toshi

Seems reasonable to me. Anyone know of a reason that wouldn't work?

The spec was originally unclear on what the valid bit meant - I think
