sierra - skylake - BIOS error when rebooting after shutdown

[Lesterix]

Hi all,

When I power on after a clean shutdown from macOS, 3 attempts to boot are made after which I end up in a BIOS screen informing me of a boot failure. Only entering the BIOS and afterwards Save & Exit results in a normal boot sequence. Exiting the BIOS without saving (although no changes were made to the config) results in a boot failure.

I am running macOS Sierra 10.12.6 on the build in my profile. Clover configuration, IOreg export and screenshot of the BIOS screen attached.

EDIT: When the computer has shut down and I switch the PSU off and on completely, it boots without any errors afterwards.

Thanks in advance for any info.

Happy hacking

Bump. Is there some more information I can supply or does nobody have a clue about the cause of this behavior?

I have read earlier that shtudown issues might be caused by PowerManagement or USB. I have the "FixShutdown_0004" DSDT patch and a "26 port USB limit" patch in my clover config. Do I need something else?
