Hello,
I'm building a custom x86_64 platform. It gets to BDS, where I select an USB with Debian as a boot device.

Here I set the serial console as a display device. Then I continue into booting the USB stick where I see 2 fatal errors.

Is this related to the SMM fatal errors? It's occurring here https://github.com/tianocore/edk2/blob/14923c1a6bf9940b48feeaf47cb5d6c662b6528c/MdeModulePkg/Library/PiDxeS3BootScriptLib/BootScriptSave.c#L829
There a lot of function calls and I can't print a stack trace.
If this is related to the SMM errors, any advice on how to fix them? If not, I guess it's off to the Debian mailing lists.
Regards,
Hristo Mihaylov

I don't know why the kernel fails to boot, but I can comment on the SMM
error messages.
BDS has to lock down SMM before it launches third party drivers /
applications. Therefore an ExitBootServices() callback ("notify
function") that attempts to write the S3 boot script, *in combination
with* a LockBox library instance that is backed by SMM, will not work.
The S3 boot script generally serves for re-initializing / restoring
platform chipset state on S3 resume, so I don't see why it should be
delayed until an EBS handler.
The Intel whitepaper
A Tour Beyond BIOS
Implementing S3 Resume with EDKII
explains the right order of steps in section "Normal Boot Flow for S3".
(The copy I have is quite dated at this point: October 2014.)
You can also refer to PlatformBootManagerBeforeConsole() in
"OvmfPkg/Library/PlatformBootManagerLib/BdsPlatform.c":
- signal the gEfiEndOfDxeEventGroupGuid event group
- call S3SaveStateProtocol->Write
- install gEfiDxeSmmReadyToLockProtocolGuid
(Speaking in terms of PlatformBootManagerLib APIs, these should occur in
BeforeConsole, and not in AfterConsole, in order to precede 3rd party
drivers/apps. EfiBootManagerDispatchDeferredImages() called in
BeforeConsole (meaning PCI oproms basically), but similarly after the
last step of the above triplet.)
Hope this helps,
Laszlo
