I will test that, but I am not convinced it can help. The crash happens in startprog64(), where the kernel is copied from (efi_kernel_start + efi_loadaddr) to (efi_kernel_start). During the process, it writes to pages allocated by UEFI, causing the crash. If I understand correctly, chaning EFI_ALLOCATE_MAX_ADDRESS will change efi_loadaddr, which means it will only change the source address for startprog64(), not the destination. -- Emmanuel Dreyfus m...@netbsd.org
