Ok, looks like your dentry lists got seriously corrupted.
The good news (?) is that you seem to have preempt enabled, and there is one known (but fairly hard-to-hit) race in UP+preempt locking due to bad barrier ordering in test9 (and all previous kernels too, for that matter). That should be fixed in the current BK snapshots, but you can also avoid the problem by just not enabling preempt.
Of course, if you see the bug without preempt, or if this was on a SMP kernel (which _should_ have hidden the preempt problem even with preempt enabled), holler.
