Source Upgrade to FreeBSD-8 Killed My ZFS Mounts

[Weaseal]

Hi all,
I did a source upgrade to FreeBSD-8.0-release today, and upon booting the new kernel, my ZFS partitions have disappeared.

<ROOT@:~># uname -a
FreeBSD relnor.com 8.0-RELEASE FreeBSD 8.0-RELEASE #0 r199960: Mon Nov 30 12:31:08 EST 2009     root@relnor.com:/usr/obj/usr/src/sys/RELNKERN  amd64

<ROOT@:~># zfs mount tank/usr/home
internal error: No such process
Abort trap: 6 (core dumped)

<ROOT@:~># zfs list
internal error: out of memory

Kernel and dmesg output are attached.

I have tried it with and without these lines in /boot/loader.conf, but get the same problem:
vm.kmem_size_max="1024M"
vm.kmem_size="1024M"
vfs.zfs.arc_max="100M"

Any hints?? Any other info I can provide?

What does # zpool status say?

What does # zpool status say?

<ROOT@:~># zpool status
internal error: out of memory

FYI rebooting to my 7.2 kernel clears up all problems and the zpool works fine - however I'd like to get 8 working all the same

Does it work with geom_bsd.ko, geom_label.ko, and
geom_mbr.ko loaded at the loader prompt or
in /boot/loader.conf ? (see how elsewhere...)

Gave it a shot...no luck though...

This is resolved. I just needed to 'make installworld' - Ironically, I was intentionally holding off on this till I trusted the kernel.
