When I compile the kernel w/ HIGHMEM64G=y, it will fail to boot.
The error message is:

Kernel panic: No init found. Try passing init= option to kernel

Perhaps an initrd error, or possibly a raid controller problem.

Do you see the driver getting loaded and scrolling by assuming it is either compiled in or as a module in the initrd image.

Some raid controllers like the Megaraid u160 cards actually map a piece of highmem between 3.5-4G for use. This means that it won't be possible to see it or address it since they overlap.

It is also quite possible that a raid/scsi controller is unable to work with 64G highmem but that shouldn't happen.

I don't make sense, I don't pretend to either. Questions?
