Fwd: [Bug 150021] New: kernel panic: "kernel tried to execute NX-protected page" when resuming from hibernate to disk

[Rafael J. Wysocki]

Hi,

The following commit:

commit 13523309495cdbd57a0d344c0d5d574987af007f
Author: Josh Poimboeuf <jpoimboe@xxxxxxxxxx>
Date:   Thu Jan 21 16:49:21 2016 -0600

    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
