Same kernel runs fine on power5. Although it does have patches

pci config space (at least not intentionaly).
I'll try again with an unpatched, unmodified kernel.
there have been a number of fixes to lockdep recently - could you try
the kernel/lockdep.c file from latest -mm, does that fail too?
one possibility would be a chain-hash collision.
