Subject: Re: 2.6.39.1 immediately reboots/resets on EFI system

So this is obviously even more of a hack, but before you check whether 
the memblock has already been reserved could you __check_region it as 
well? That ought to avoid us touching the kernel. I've got a patch for 
grub that'll avoid the situation where we load the kernel on top of an 
existing resource and I'll port that to grub2, but that's still going to 
be awkward for existing bootloaders.
