This is my understanding. I made the below changes and got the new log: + staging =3D 0x40000000; /* 1GB */ - status =3D BS->AllocatePages(AllocateAnyPages, EfiLoaderData, + status =3D BS->AllocatePages(AllocateMaxAddress, EfiLoaderData, STAGE_PAGES, &staging); efi_copy_finish: calling trampoline efi_copy_finish: staging=3D3d000000 efi_copy_finish: staging_end=3D40000000 efi_copy_finish: staging_offset=3D3ce00000 efi_copy_finish: src=3D0x3d000000, dst=3D0x200000, last=3D0x40000000 ... trying to write: 0(0x3fd72fe0) to 0(0x2f72fe0) trying to write: 0(0x3fd72fe8) to 0(0x2f72fe8) trying to write: 0(0x3fd72ff0) to 0(0x2f72ff0) trying to write: 0(0x3fd72ff8) to 0(0x2f72ff8) trying to write: 0(0x3fd73000) to 2f74023(0x2f73000) Dexuan: Crash!!! --=20 You are receiving this mail because: You are the assignee for the bug.=
