[Cbe-oss-dev] Badness at kernel/lockdep.c:2465

[Andrea]

I have finally managed to run a new kernel 2.6.32.2
I've used a basic ps3_defconfig + some extra changes.

Then in the boot log I can see the following. It does not seem to be problematic since everything
works afterwards, but someone might be interested.
