Hi,

This problem exists on v3.6-rc1 also. I bisected the crash below to:

f1d2c07d331f717da79a42952be7dc1c0d35f846

It's a merge commit, Merge tag 'boards' of
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

I'm not sure why bisect did came up with a merge commit, instead of the
actual code commit, though.

I don't see any changes in overo's board file that could cause this, so
could it be an omap3 wide problem? Although I would think somebody else
had noticed it also, then.
