On my system, also labelled as a Dell Precision M4500 although it's a development system so could be a bit different, GRUB shows the set_virtual_address_map function as being at address 0xbb65d280. I wouldn't be surprised if my memory map was a bit different from yours, but this is still in the bottom 4GB of memory rather than way up at the top.
I notice this in your log, which is odd and suggests a problem: [ 0.000000] Kernel-defined memdesc doesn't match the one from EFI! I'll look into this more when I can. -- No UEFI boot on Dell Precision M4500 https://bugs.launchpad.net/bugs/635439 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
