From: Mihai Carabas <mihai.carabas@oracle.com> stable inclusion from stable-v5.10.96 commit c534287a57dc32d89428f10a06650086a4290521 bugzilla: https://gitee.com/openeuler/kernel/issues/I55NWB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit e9b7c3a4263bdcfd31bc3d03d48ce0ded7a94635 ] The kernel is aligned at SEGMENT_SIZE and this is the size populated in the PE headers: arch/arm64/kernel/efi-header.S: .long SEGMENT_ALIGN // SectionAlignment EFI_KIMG_ALIGN is defined as: (SEGMENT_ALIGN > THREAD_ALIGN ? SEGMENT_ALIGN : THREAD_ALIGN) So it depends on THREAD_ALIGN. On newer builds this message started to appear even though the loader is taking into account the PE header (which is stating SEGMENT_ALIGN).
