Can you try to reproduce it with WITNESS and *without* WITNESS_SKIPSPIN? I would need to look at "show alllocks" and possibily "ps" because it seems that the lock owner is preempted but it should not happen while holding a spinlock (unless the acquired spinlock is the one in the preempting path, in this case thought it should drop inside sched_switch() and we can try to understand why that doesn't happen).
