----------------------------------------
Per request, adding new ticket for an issue with my t440p where attempting to 
resume on suspend results in a reboot (or at least, not resuming from DRAM).

My t440p already has coreboot installed (via osbmk). Following instructions 
from issue #412, I have attempted the following:

`sudo flashrom -p internal --ifd -i bios -w the_full_12MiB_osbmk.rom 
--noverify-all`

...but that did not seem to do the trick (still "restarts" without resuming 
from RAM).

Note that I am using the "full" 12MB osbmk rom (not split by 4MiB and 8MiB, as 
that seemed intended for the hardware flashing instructions).

coreboot version looks like 4.15.204, and flashrom version 1.2-640.

If it helps, attached cbmem -1 output with a "normal boot" followed by a later 
resume from suspend (that resulted in a restart).

Thanks in advance. I guess you don't realize how much you use suspend until it 
doesn't work anymore :)
