Description
The following assert happened today with about two weeks old debug build (changeset b045990). It means that I do not have these recent ZFS fixes: #5592, #5531, #5562, but my panic stack does not look similar, hence reporting.

Happened again with a nightly from 2015-Feb-20 (changeset e6cb0f7):
