As I recompiled stuff, here's the current failure log: http://bues.ch/misc/linux-3.0-pbook-2.jpg And this is the corresponding readelf output: mb@maggie:~$ readelf -a /boot/linux.a ELF Header: Magic: 7f 45 4c 46 01 02 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, big endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: EXEC (Executable file) Machine: PowerPC Version: 0x1 Entry point address: 0x400230 Start of program headers: 52 (bytes into file) Start of section headers: 5769716 (bytes into file) Flags: 0x8000, relocatable-lib Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 2 Size of section headers: 40 (bytes) Number of section headers: 12 Section header string table index: 9 Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .text PROGBITS 00400000 010000 0048b0 00 AX 0 0 4 [ 2] .data PROGBITS 00405000 015000 0012f8 00 WA 0 0 4 [ 3] .got PROGBITS 004062f8 0162f8 00000c 04 WA 0 0 4 [ 4] __builtin_cmdline PROGBITS 00406304 016304 000200 00 WA 0 0 4 [ 5] .kernel:vmlinux.s PROGBITS 00407000 017000 569952 00 A 0 0 1 [ 6] .bss NOBITS 00971000 580952 00bc70 00 WA 0 0 4 [ 7] .comment PROGBITS 00000000 580952 00001c 01 MS 0 0 1 [ 8] .gnu.attributes LOOS+ffffff5 00000000 58096e 000014 00 0 0 1 [ 9] .shstrtab STRTAB 00000000 580982 000072 00 0 0 1 [10] .symtab SYMTAB 00000000 580bd4 000780 10 11 55 4 [11] .strtab STRTAB 00000000 581354 0004f3 00 0 0 1 Key to Flags: W (write), A (alloc), X (execute), M (merge), S (strings) I (info), L (link order), G (group), x (unknown) O (extra OS processing required) o (OS specific), p (processor specific) There are no section groups in this file.
