if gcc-4.6 was from meta-toolchain (including linaro patch
toolchain-layer/recipes-devtools/gcc/gcc-4.6/linaro/gcc-4.6-linaro-r106827.patch)
then you need to pass -mno-unaligned-access in your kernel Makefile
like this commit does:
http://git.freesmartphone.org/?p=linux-2.6.git;a=commit;h=78ffc81db8911acdabd026ad3fdefa20b4e34e52

be aware that without this patch -mno-unaligned-access is not valid
option for gcc (older than 4.7).

Cheers.
