For me the (rather old?) kernel from
git://git.linaro.org/people/ronynandy/linux_stable.git also has issues
with sata. In dmesg you'll find a stream of error messages, which you'll
find to be fixed in later kernel version. I don't have the error
messages at hand.

A vanilla kernel.
I've tried to compile vanilla kernels, but can't seem to enable sata
support. This was about three weeks ago. Right now the arndale is in the
corner, I'll try again with kernel 3.10, as that might have improved
exynos support according to
