I've been diagnosing a failure to boot on a Samsung Galaxy Book2 (W737)
but have not been able to get the kernel to boot, and would welcome some
assistance:
EFI stub: ERROR: Exit boot services failed
The problem occurs in
drivers/firmware/efi/libstub/efi-stub-helper.c::efi_exit_boot_services().
EFI_INVALID_PARAMETER is returned by efi_bs_call(exit_boot_services...).
Based on reading the EDK source I suspected either the key was changing
or memory alignment is wrong based on a reading of EDK's
CoreExitBootServices() and CoreTerminateMemoryMap() - making a large
assumption that Lenovo/Aptio (American Megatrends) firmware is based
around EDK.
Since the addition of commit d4b341269efb3 "arm64: dts: qcom: Add
support for Samsung Galaxy Book2" I had inferred it is now possible to
boot this device into Linux, but so far it seems not.
I added extensive efi_debug() logging to try to identify the problem and
have reported the patches I'm using and results extensively (too
extensively for including in this email) at "Issue #11: Samsung Galaxy
Book2 (SM-W737Y) snapdragon 850" of the aarch64-laptops project:
