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

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.
