Can someone please tell me the correct procedure to get my

Thanks a lot

Ouch!  Before you read any further, let me state
in no uncertain terms that I am not an expert!
Did you also make a world for the new target
architecture?  It would probably not be a
Good Thing(tm) to have a kernel built for amd64
trying to work with an i386 userland, and that
could be a possible, even likely,  explanation for
the failure to mount the fs 
My tentative advice: Boot up with the old kernel,
**make a complete backup**, and then either:
A Try again with a full buildworld/buildkernel etc,
routine, OR:
B Contact the freebsd-amd64 list with a new
question.
I'd probably recommend the latter first ...

FreeBSD 5.3; hoto migrate from i386 to amd64 mode

hello folks,

Now I want to use the full power of my 64 bit CPU. I cross compiled the kernel 
to amd64 mode (cd /usr/src; make kernel TARGET=amd64 TARGET_ARCH=amd64 
KERNCONF=REINEKE64) and tried to reboot the machine with the new kernel. The 
kernel himself seems to work but when he tries to mount the root filesystem the
