grub-efi-amd64 on Debian Jessie,

Works with 0.6.3 (v0.6.3-766_gfde0d6d)
Does not work with 0.6.3 latest code (dailies version). 

Tested on VitualBox (v4.3.20 r96997) with,

UEFI partition on sda1
ZFS on sd[a-d]2
/boot either on (ext4 RAID 1, sd[a-b]3) OR (ext4 RAID 10, sd[a-d]3) OR (zfs)


Pool was create with,
zpool create spool mirror /dev/disk/by-id /dev/disk/by-id mirror
/dev/disk/by-id /dev/disk/by-id

After system setup, initrd.img-3.16.0-4-amd64 was regenerated:
update-initramfs -c -k all

'update-grub' was run to rebuild grub.cfg and the following line was
added/corrected if missing/incorrect:
root=ZFS=spool/ROOT/debian

Also tired manually entering different combination of the following through
the grub boot menu while trouble shooting:
boot=zfs rpool=spool bootfs=spool/ROOT/debian

For example:
linux /vmlinuz-3.16.0-4-amd64 root=zfs=spool/ROOT/debian ro quiet boot=zfs
rpool=spool bootfs=spool/ROOT/debian



***

At first reboot, the screen freezes with the following message:

mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
/init: line 335: can't open /root/dev/console: no such file
...
[end Kernel panic - not syncing: attempting to kill init!
exitcode=0x00000200

After a cold boot the following message appears:

sh: argument expected <- repeated 4 times

Command: mount -o zfsutil -t zfs - /root
Message: filesystem '-' cannot be mounted, unable to open the dataset
mount: mounting - on /root failed: No such file or directory
Error: 1

Manually mount the root filesystem on /root and then exit.

BusyBox v1.22.1 (Debian ...

/bin/sh: can't access tty; job control turned off
/#



***

NOTE: When I don't add "boot=zfs rpool=spool bootfs=spool/ROOT/debian" in
the grub menu boot command line, the boot message is slightly different:

modprobe: module unknow not found in modules.dep
mount: mounting ZFS=spool/ROOT/debian on /root failed: no such file or
directory
mount: mounting /dev on /root/dev failed: No such file or directory
Target filesystem does't have requested /sbin/init.
no init found. Try passing init- bootarg.
modprobe: module ehci-orion not found in modules.dep

/bin/sh: can't access tty; job control tuned off

A likely fix is to use patches that work with the MBR patched version of
grub (2.02~beta2-9) tested to works with the latest ZoL code (dailies
version).
