zfs discuss - Jun 2006 - snv_42 zfs/zpool dump core and kernel/fs/zfs won''t load.

I''m pretty sure this is my fault but I need some help in fixing the
system.

It was installed at one point with snv_29 with the pre integration 
SUNWzfs package.  I did a live upgrade to snv_42 but forgot to remove 
the old SUNWzfs before I did so.  When the system booted up got 
complaints about kstat install because I still had an old zpool kernel 
module lying around.

So I did pkgrm SUNWzfs and SUNWzfskr SUNWzfsku SUNWzfsr (ie the old and 
the new).

I then rebooted, all okay.

Now I need to get ZFS bits on here so I pkgadd SUNWzfs* from the snv_42 
Solaris_11/Product directory.  All goes fine but zfs(1) and zpool(1) 
dump core because /dev/zfs doesn''t exist - because kernel/fs/zfs
didn''t
load.

Here is some more info, can some one help me fix this up.  For internal 
to Sun people this is ardbeg.sfbay
