This seemed to start happening sometime after RC1. 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.
