Unfortunately it seems a lot of boards are affected by this. A88XM-E and Lenovo G505S (AMD fam15h) also got broken: they rarely succeed at booting - and, when they do, no boot devices are available (virtual floppies too, for some reason) - except coreinfo/tint secondary payloads which became prone to freezing. I attach the A88XM-E logs I've been able to obtain with USB FT232H:
- ok_e6fb1344ed9188e19be4b54bdf1a76680b8c4523.txt - last coreboot
repo's revision where all the stuff works 2) fail_1_3b02006afe8a85477dafa1bd149f1f0dba02afc7.txt - this commit got the boards broken for the first time 3) fail_2_6b95507ec5b087658178a325bdc68570bc48bb20.txt - this is a log for coreboot's master top
For some reason logs for 2) and 3) always stop after "PCI: 00:12.2 EHCI Debug Port hook triggered".
I hope these commits could be reverted before we figure out what's going on with them. Good thing we've noticed it fast enough.
Thanks, Mike. The amd chipset code (all of it from what I can tell) is fundamentally broken and at odds with all of the resource allocation flow. They worked previously because dynamic resources were being assigned using an algorithm that just assumed there weren't collisions, and that was done w/o all the necessary info required for making the proper decisions regarding dynamic resource allocation.
I landed the other chipsets' fixes, but the amd chipset code is going to take a lot more to fix. Would you be willing to test patches as they are crafted? Given the largeness of the problem as well as the gnarly code that is the amd chipset code it's going to take some time so I think we do need to revert the allocator changes until we can do some house keeping.
I just was brainstorming with Furquan. He did push the revert changes, but we were scheming on a patch that I was hoping affected parties could try in conjunction with https://review.coreboot.org/c/coreboot/+/41363. Basically we'll allocate top down like the previous allocator did hoping for no collisions. Let's try that, and see where we land. Regardless we need to fix this amd chipset code as it's a major liability.

Hi guys,
31ab7de51a is CB:41368, cherry picked into my local repo.
Turns out I have to back out all four of Furquan's patches (CB:39486~39489) for my board to boot normally again.
Thoughts?
I'll now get a log with everything in at SPEW.

Keith, is it possible to have the console log level set to SPEW? I'm

I see 'Setting RAM size to 768 MB' which means I would expect to see
a hole in the ranges representing 768MiB.
that would be bad. I don't know what commit '31ab7de51a' is, but it
might not contain the CB:41368. Having SPEW logs would be helpful.
Also, what mainboard Kconfig are you selecting for p3bf?
src/mainboard/asus/p2b ?

Hi Aaron,
Here is a log with everything including CB:41368 included. I'll get this log out to you first, while I try a build with all problem commits left out.
Thanks Keith

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.

The patch link I sent was based off of someone else's mainboard logs.
