X201 restarts rather than waking up
With coreboot 4.8.1 (and with the current git master) my X201 no longer wakes up from suspend-to-RAM, i.e. instead of resuming it boots from scratch. Sometimes (but not always) when this happens, the "moon" LED starts blinking.
The laptop works fine with coreboot 4.6 but fails entirely to boot with version 4.7 thus I can't easily figure out which commit broke it.
Is there anything I can do to help debugging this?

@Alexander Couzens: Sorry for the delay, I completely forgot about this. The option that causes the issue (still does in 4.9) is CONFIG_CONSOLE_SERIAL. When I enable that, the resulting ROM will crash instead of waking up; when I disable it, everything runs just fine.
Let me know if I can do anything to analyze this further.
