It'd probably help if you could give us more details on the kernel

Can you see where it is panicking?  Does it happen during the
kernel/initrd stage or later during boot?

I suggest installing the kdump service if it is panicking later in
boot, you might be able to capture a kernel dump which makes debugging
these things a lot easier.  Otherwise, I suggest trying to capture the
panic message some other way.
