--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> ---
This has all the indications of a mis-aligned memory access.  Since you're on
Linux, please make sure that the 'User faults' field in /proc/cpu/alignment
shows a value of 2 (fixup) or 3 (fixup+warn).  You can 'echo 3 >
/proc/cpu/alignment'
in your startup scripts to ensure this setting, or you can hack it into the
kernel source's arch/arm/mm/alignment.c (which is what I do).
