Hi,
First of all, I'm not the right person to report these problems to.

The issue above should better be reported to the people on
linux-ide@xxxxxxxxxxxxxxx , as no one else really can take care of it.
Still, I think there's a known way to solve this problem, since I've never
seen it myself and I happen to install Linux quite often on notebooks.
What distribution do you use?

I _think_ the problem is that one option (or more) in your config selects
the HIGHMEM64. As I told you previously, I've never seen this problem myself,
most likely because I've been building kernels on 64-bit machines for quite
some time now.
Nevertheless, you can report it to Michal Marek <mmarek@xxxxxxx>, who's our
new kbuild maintainer.
