Thanks Furquan.
Here are 3 logs. Log 1 is at the commit just before the problem. Log 2 is at the problem commit. Log 3 is at the current master, if that's what you meant by ToT.
I'm using SeaBIOS 1.13.0, compiled once using the attached .config before taking these logs. All 3 runs are taken using the same SeaBIOS binary.
Then I recompiled SeaBIOS with CONFIG_RELOCATE_INIT off, replaced the payload used in run 3, and took an extra run. In this case the board reset on its own at "Scanning option roms", looping infinitely.
Hope this helps Keith

Dear Keith,

I am still refining the P2B family of boards, now including the infamous P3B-F with an unusual appetite for hacks to make work.
That said, I'm now finding that, on P3B-F, SeaBIOS hangs when it tries to relocate itself as part of its usual chores. Having just learned git bisect, I decided to try it out.
It was commit 3b02006afe8a85477dafa1bd149f1f0dba02afc7 [1] that broke my SeaBIOS. It doesn't affect my newer toy the P8Z77-M as much as P3B-F, but I still want to blame that, and probably the very next commit as well, as they both deal with some very modern aspects of PCI that well predates the 440BX.
Is there anything we can do to fix 3b02006afe?
I commented in the change-set [1] to make the author and reviewers aware of this issue and referenced your list message, and ask to comment here.
Could you please provide the debug log of coreboot and SeaBIOS?
As Paul mentioned, can you please provide the debug logs for coreboot and SeaBIOS both with ToT coreboot and with HEAD set before the change 3b02006afe where it does not hang? Thanks!
Meanwhile I ported the P3B-F board enable to flashrom [2], which got a heavy workout during this bisect, through vendor firmware and both good and bad builds of coreboot. In all cases I can flash internal, no longer having to haul out my P2B-LS just to use it as a flasher.
Enjoy this long overdue board enable. If it gets submitted, I'll retract the ramstage hack[3] doing the same as redundant.
Very nice! It’s always amazing, how after so many years, when the vendor already stopped supporting the device, the community still supports the device and improves the firmware showing that Free Software is the more sustainable way.
Kind regards,
Paul
