No luck. However, I added an ASSERT_VOP_LOCKED() to vn_statfile(), and confirmed that vn_lock() fails to lock the vnode. Unfortunately, without a dump it's hard to tell exactly what kind of vnode we're dealing with. I thought the problem might be an incorrect vop_lock implementation in devfs (the only synthetic filesystem mounted on the box), but devfs uses std_{islocked,lock,unlock}, and visual inspection didn't uncover any obvious flaws in any of those. Any other suggestions before I just turn off DEBUG_VFS_LOCKS?
