Also, I'm > curious if you only see this with SUJ or if plain UFS+SU works fine? The crash on demand right now is producable on 8.x and 9.x, so SUJ isn't a requirement. Also, there is no crashdump available. The OS just hangs and stops taking input. There's no panic or coredump or anything of the like. You just have to nuke the VM and re-boot it back up. And for the record we can't reproduce this crash in Xen...
