bug#24087: recovery from suspend is broken with recent libreboot + linux-libre 4.7

[ng0 <ng0@we.make.ritual.n0.is>]

This is the boot up messages of one of the affected (running GuixSD)
devices. As I was assured this is a GuixSD specific problem, parabola,
trisquel and others do behave as expected (recover from
suspend/hibernate works).


Jul 28 15:32:29 localhost vmunix: [    0.000000] KERNEL supported cpus:
Jul 28 15:32:29 localhost vmunix: [    0.000000]   Intel GenuineIntel

Jul 28 15:32:29 localhost vmunix: [    0.000000]   Centaur CentaurHauls

I am used to individual configured kernels, so this might be just my
impression. Should this not be more specific, include core2 etc, or is
this just a listing of vendors there and not the cpu selection I
remember from the makemenuconfig dialog?

Then further on there's a call trace, this will be pasted here and leave
out some lines because I don't like to be that transparent in clear
public communication about my hardware.  Then again I don't know how
much this will tell, so if anyone says it's easier to debug with the
full information provided, I could do so.  This trace happens every time
I boot:
