The latest diff does not crash on amd64. That's the good news. Even better news is that the hang that I had with enabled ZIL under heavy load now seems to be gone. The build that was usually triggering the hang after about an hour has been going for about three hours now. Thanks a lot for the diff. It does help to bring ZFS on FreeBSD closer to production quality. --Artem
