Hi,
Today I faced again the same isse with the same error. Searching web by term "x86/mm: Checked W+X mappings: FAILED" I stumbled upon this bug again. And no answers.
After some hours working in my VM to try to fix this issue, I found the root cause. It is some bug between xen and grub.
My VM is running on Stretch now, but it has been running Debian and been upgraded for a very long time. So it was running on grub version 1.
After all the troubleshooting, I copied everything from a running rescue disk: kernel, initramfs, modules, etc. The only missing part was grub. So I upgraded to grub2 and... fixed!
So this nasty problem is some bug on xen and grub version1, which can't handle something the new kernels have.
I'm attaching the screenshot since the crash is to fast to save as text. Color blue wasn't intended, but made it very alike a BSD :)
I'm implementing DKIM on my mail server, so some disturbance is expected.
