Kirill A. Shutemov 1b3a626436 x86/boot/compressed/64: Validate trampoline placement against E820 ... There were two report of boot failure cased by trampoline placed into a reserved memory region. It can happen on machines that don't report EBDA correctly. Fix the problem by re-validating the found address against the E820 table. If the address is in a reserved area, find the next usable region below the initial address.
