Hi,
Missing a lot of context here.

"Couldn't get size:" is from security/integrity/platform_certs/load_uefi.c.
The "size" that is printed appears to be EFI_NOT_FOUND, so it seems that
some error handling is not happening.

#define EFI_NOT_FOUND		(14 | (1UL << (BITS_PER_LONG-1)))

Adding a few cc:s.
