Hi,
The following commit:
commit 13523309495cdbd57a0d344c0d5d574987af007f

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
