There's some similarity to kern/209816, but mine are on unmount. FreeBSD xx 11.0-ALPHA5 FreeBSD 11.0-ALPHA5 #0 r302164: Fri Jun 24 = 02:51:52 UTC 2016 = root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 1st 0xfffff80007cd0b78 zfs (zfs) @ /usr/src/sys/kern/vfs_mount.c:1222 2nd 0xfffff8002d33d418 zfs_gfs (zfs_gfs) @ = /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/gfs.c:484 More details (with stacks) are at https://gist.github.com/mfplass/fe9c6b84a8f14839bbc2b2b2e03272ca It seems to happen on shutdown. I don't think I've seen it hang. The log shows one involving ufs instead of zfs, unfortunately without a = stack. I'm not sure why that is, unless it was the installation memstick. There's another, probably unrelated, LOR that I'll put in a second = message. Thanks, - Michael=
