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.
$ sudo dmidecode
Password:
# dmidecode 2.12
SMBIOS 2.7 present.
8 structures occupying 382 bytes.
Table at 0xBDAB4020.

Table is unreachable, sorry.
