OK, this is good, it means the bisection domain isn't too big.

Can you remember if you made any kernel configuration change between
2.6.38 and 2.6.39?

I see you have many debug options enabled. I suggest you try building a
kernel without these and see if it makes a difference.

If you can't get a serial console to capture the complete error log,
the other approach is to bisect between kernels 2.6.38 and 2.6.39, to
find the faulty commit. If you're used to building your kernel
yourself, it shouldn't be too difficult. Just clone Linus' kernel tree
and follow the git bisect manual page:
