[Bug 2078307] Re: Grub 2.12 in Oracular is unable to boot Windows using chainloader

[Mate Kukri]

@resonic thank you for reporting this, I think you have found a real
issue with the new NX enablement stack in Oracular.

I have created
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/2084104, as I am
pretty confident in my theory, and I'll also try to verify the above
theory tomorrow.

Thankfully the only impact should be Windows chainloading with Secure
Boot disabled, but it still sounds like a real bug we need to fix and
will fix.
