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

[Danny Milosavljevic]

Hi,

I have a X200 and some time after waking up from suspend on the first larger 
disk access it hangs, losing all the dirty sector payload in the process. This 
is Guix-specific, the same machine works just fine on Ubuntu.

I don't update the BIOS (I disabled the ability to do so in the chip settings).

Given the ability for an update to brick, I only flashed it once before there 
was any data on the machine - and I don't plan on doing it again on this 
machine.

I do actual work on this machine and were it not booting it would be much worse 
than wakeup not working.

I sometimes non-thinkingly close the laptop lid so it crashes from time to 
time. So if logs help I can provide those.

Also, dmidecode stopped working some time ago so I can't check which libreboot 
version I have.
