--- Comment #73 from commit-h...@freebsd.org --- A commit in branch stable/12 references this bug: URL: https://cgit.FreeBSD.org/src/commit/?id=f131d68e21fc360f5c8e63377f25cf60706d9afa commit f131d68e21fc360f5c8e63377f25cf60706d9afa Author: David Sebek <dase...@gmail.com> AuthorDate: 2022-01-07 20:18:49 +0000 Commit: Konstantin Belousov <k...@freebsd.org> CommitDate: 2022-01-09 01:28:01 +0000 efi: loader: Inline copy_finish function in amd64 trampoline Instead of calling the efi_copy_finish function from amd64_tramp, include the copy instructions in the trampoline code itself. This avoids boot hangs and restarts in the cases when the efi_copy_finish code happens to be located at a memory location that is overwritten during the copy process. This is a direct commit to stable/12 since no-copy loader mode requires the kernel update not suitable for the branch.
