Description

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?

SeaBIOS 1.11 with CONFIG_SERCONN is known to break S3.

Could you paste a coreboot log of when coreboot rebooted instead of resumed from S3?

Ah nice, thank you removing the serial port console option seems to have resolved this for me. Are you still interested in the logs?

Btw, feel free to close this one, I can't seem to.

The underlying problem needs still be fixing in my opinion. But it’s not clear yet, if it’s coreboot’s or SeaBIOS’ fault.

@Stefan Ott: Which serial power do you enabled? In coreboot or/and in seabios? we should exclude then from all target not supporting a serial at all.
