Unfortunately, I had the option already enabled when using the "config-unreliable" in my initial posting. So it looks like this setting is not effective in stopping the hangs.
After further external analysis once the KGPE-D16 was placed on our test stand for OpenBMC development, the intermittent hang resulting in hard system lockup (requiring a full standby power cycle) appears to be fixed in this patch series on Gerrit:
Can you please test and confirm?
Sure thing: I applied the patch on top of current coreboot-master and compiled the ROM using the "config-unreliable" from my initial posting. Then I did a series of five warm reboots and watched the output on the serial console. Result: No more hangs! (Previously, it took like 20 attempts to get even one successful boot)
Great job, and many thanks!
