Does anyone have a clue what's going wrong, or even how to fix it?
Which kernel are you using. From bnutils release note,
---
Starting from the 2.17.50.0.4 release, the default output section LMA
(load memory address) has changed for allocatable sections from being
equal to VMA (virtual memory address), to keeping the difference
between
LMA and VMA the same as the previous output section in the same region.
For
.data.init_task : { *(.data.init_task) }
LMA of .data.init_task section is equal to its VMA with the old linker.
With the new linker, it depends on the previous output section. You
can use
.data.init_task : AT (ADDR(.data.init_task)) { *(.data.init_task) }
to ensure that LMA of .data.init_task section is always equal to its
VMA. The linker script in the older 2.6 x86-64 kernel depends on the
old behavior. You can add AT (ADDR(section)) to force LMA of
.data.init_task section equal to its VMA. It will work with both old
and new linkers. The x86-64 kernel linker script in kernel 2.6.13 and
above is OK.

Does your kernel link script follow my release note?
