We'll likely need coreboot debug logs. You can get one for normal boot using the tool under utils/cbmem, that might help us already. To collect log from failing S3 resume you need to learn about usbdebug and possibly get some FT232H or beaglebone hardware.
I'll attach the cbmem log, both for a clean boot and a boot that happens instead of the expected resume.
It's likely I already have all I need for USB debugging at home; I will check when I get home tomorrow. Is it simply a serial console via FTDI?
Also check ifdtool -d output. S3 resume requires host CPU has write access to the part of SPI flash where MRC cache is located.
It should be okay; I unlocked all regions using ifdtool. And flashrom can write the whole 12MB without problems. ifdtool -d does not mention anything about MRC cache, though; I'll attach that, too.
