Thanks, Denys. Interesting point about gcc. It's version 4.8.1 which is the default for poky master. Which is what I used all along.
Thanks for sending your binaries. They fail too with the exact same problem. See attached log. I found [1] on gmane which exactly describes the problem I am seeing. If that is the case then I was wondering why my earlier builds with 3.12-rc3 actually worked. And I tried them again and they are now failing too. Of course I don't know anything about the specifics of the gpio and the timers on the chip but it looks like a weird hardware initialization condition. And I don't know if the proposed patch in [1] was ever incorporated in your kernel tree. I don't think it's the hardware (or at least not alone) because the SD that ships with it with the 3.2 kernel works just fine.
