Hi,

The following commit:

commit 13523309495cdbd57a0d344c0d5d574987af007f
Author: Josh Poimboeuf <jpoimboe@redhat.com>

    x86/asm/acpi: Create a stack frame in do_suspend_lowlevel()
    
    do_suspend_lowlevel() is a callable non-leaf function which doesn't
    honor CONFIG_FRAME_POINTER, which can result in bad stack traces.
    
    Create a stack frame for it when CONFIG_FRAME_POINTER is enabled.

is reported to cause a resume-from-hibernation regression due to an attempt
to execute an NX page (we've seen quite a bit of that recently).

I'm asking the reporter to try 4.7, but if the problem is still there, we'll
need to revert the above I'm afraid.

Thanks,
Rafael

last working .config

Overview: 

When commit 13523309495cdbd57a0d344c0d5d574987af007f is applied to my kernel
sources my kernel panics when trying to resume from hibernate to disk.


Steps to Reproduce: 

1. have a working hibernate/resume setup
2. compile 4.6.x kernel
3. boot and hibernate to disk
4. test various kernels using "git bisect".


Actual Results: kernel panics when trying to resume from hibernate to disk.

Expected Results: Resume from hibernate to disk like kernels without commit
13523309495cdbd57a0d344c0d5d574987af007f did.


I attached my working .config of my 4.5.7 kernel.

Any help will be appreciated. Thanks!
