Your trace shows that a context switch occurs while a thread is still holding a mutex. It isn't clear which thread is that. The traces shows that a userland process gets preempted via Xsyscall/ast /preempt. Which raises the question: is the assertwaitok() happening too late? If you can easily reproduce the problem, please enable WITNESS in your kernel and try again.
