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
Hi,
I don't owe the server. Just have a VM that was running flawless with
Debian since Squeeze.
And for the first time Debian became a sour option.
I was going to compile another kernel when I found also kernel-package
isn't released because of unwatched issues.
Best Regards,
Helio

Please provide a full serial log when booting with the bad kernel.
Also please let us know what version of Xen you are running and whether
this was running as a guest or as dom0.

Hi,

And in the first post in this bug it says:

Nowhere there does it say anything about failing to b
Hi,
It can't be. It is the same bug as describe in this one.
If you read the first post, it can't boot and shows the same content as in
the bug I detected now on my system.
So it isn't a new bug. It was introduced since kernel 4.4 became available
on upstream and not handled.

Hi,
And `reportbug kernel` won't work cause it requires the system or kernel
to be up and running. It isn't the case. This bug is leading the system
to an outage on boot.

This option does not (per its intent) present booting, it is just a
check & warning.
There may be a bug with the check which is causing a failure to boot,
but you are the first to report that aspect and that isn't what #852324
was about until now.
Please use `reportbug kernel` to report a fresh b
Hi,
VM doesn't boot with this parameter enabled, as confirmed by Linus mail.
So my upgraded to Stretch leaded to a complete system outage because of
this parameter.
I held on kernel 3.19 from Jessie meanwhile.

Hi,
As much it sounds correct to protect systems in this way, you broke
compatibility. I'm back to kernel 3.19 until this is fixed.
So in order to have such parameter enabled, you should at the least provide
a bootparam option to toggle enabled or not.

Hi,
First an errata: I don't see messages since March, not January as I stated
wrongly before.

Linus himself about a way to avoid such error:
