Are you able to catch dmesg up to mount failure?
If yes, then please set vfs.zfs.debug=1 in loader.conf or at the prompt and 
share
the messages.

FreeBSD 9.1-BETA1 amd64 fails to mount ZFS rootfs with error 2 when system has more than 3584MB of RAM

[Richard Yao]

Dear Everyone,

I am running FreeBSD 9.1-BETA1 amd64 on ZFS in KVM on Gentoo Linux on
ZFS. The root pool uses ashift=13 and is on a single disk. The kernel
fails to mount the root filesystem if the system has more than 3584MB of
RAM. I did a manual binary search to try to find the exact upper limit,
but stopped when I tried 3648MB.

FreeBSD 9.0-RELEASE works perfectly.

Yours truly,
Richard Yao
