Ok.  So we must have a relocatable kernel that figures it has been
relocated.  Interesting.  

What is your bootloader?
What is your kernel version?
What is your kernel config?

The only time I would expect to see what you are seeing is if
you are debugging the kdump kernel, which doesn't sound like
the case.

If we actually have a truly offset kernel then while things
may not be perfect this is at least expected.  I don't think
I have heard of anyone handling this case very well.

Long enough ago that I don't remember when ;)
