Hi guys,
I tested these fixes on my board, and I have to say there's still something wrong. They did address the hang or reset in SeaBIOS I first described, but now either my ATA hard drive failed to boot (it tried to hand off to GRUB on my drive, but didn't get there), or it can't find the option ROM of my video card, meaning no display.
Now I want to try the other way, testing a build with all changes related to the problem backed out instead. So besides the one I first identified, what other related patches should I try backing out?
Just go to the parent of the identified patch. As for the other symptoms you are seeing, I'd love to see logs with the patches we identified so we can root cause.
Thanks.

OK. I'll take a look at your logs and see what's going on. The patch
link I sent was based off of someone else's mainboard logs.

Hi Aaron,
It didn't help. There still a way out of whack entry in the coreboot table and e820 entry ending at 000003ffffffffff, which I think have more to do than the 41363's scope.
