I tried 8-STABLE and it's happening there too right now. I think whatever caused this was MFC'd. I've also reproduced this on completely different hardware running a single disk ZFS pool. I'm getting this output in dmesg after these hangs I keep seeing. uma_zalloc_arg: zone "pfrktable" with the following non-sleepable locks held: exclusive sleep mutex pf task mtx (pf task mtx) r = 0
