The VERIFY(BP_GET_DEDUP(bp)) panic hasn't reoccurred (tended to happen on poudriere-build cleanup), which may lean it more towards corruption, or maybe I just haven't been "lucky" with my small random chance of corruption. I did set vfs.zfs.dmu_offset_next_sync=0 after the bsdinstall was complete (maybe I could have loaded the zfs kernel module from the shell and set it before things kicked off).
