Subject: Re: [PATCH 2/2] x86/xen: Disable DMI parsing in Xen kernel.


Actually scratch this patchset -- its not sufficient. For example
ddcprobe in userspace causes the exact same issue vs 0xa0000.

Looks like the only sane solution will be to mark regions between
640K-1M reserved early on in boot.
