Serial driver version 4.27 with no serial options enabled ttyS00 at 0x12000000 (irq = 16) is a 16550A RAM disk driver initialized: 16 RAM disks of 4096K size RAMDISK: Compressed image found at block 0 attempt to access beyond end of device 01:00: rw=0, want=8196, limit=4096 dev 01:00 blksize=1024 blocknr=8195 sector=16390 size=1024 count=1 EXT2-fs error (device ramdisk(1,0)): read_block_bitmap: Cannot read block bitmap - block_group = 1, block_bitmap = 52428800 attempt to access beyond end of device 01:00: rw=0, want=16386, limit=4096 dev 01:00 blksize=1024 blocknr=16385 sector=32770 size=1024 count=1 EXT2-fs error (device ramdisk(1,0)): read_block_bitmap: Cannot read block bitmap - block_group = 2, block_bitmap = 20971520 attempt to access beyond end of device 01:00: rw=0, want=24580, limit=4096 ... (and so on) ... (later) VFS: Mounted root (ext2 filesystem). Freeing unused kernel memory: 40k init 28k prep 4k pmac 12k open firmware ... ... (last) EXT2-fs error (device ramdisk(1,0)): ext2_read_inode: unable to read inode block - inode=4001, block=16389 Kernel panic: No init found. Try passing init= option to kernel. Rebooting in 5 seconds.. ... The fs image contains no shell at the moment, so the last kernel panic is okay. What is the Problem with EXT2-fs error ? I used the following script on my x86 host (<- the problem ?) to build the compressed image: #!/bin/sh dd if=/dev/zero of=/dev/ram bs=1k count=4096 mke2fs -m0 /dev/ram mkdir -p /mnt/ram mount /dev/ram /mnt/ram (cd file_system; cp -a * /mnt/ram) umount /mnt/ram rmdir /mnt/ram dd if=/dev/ram of=fs_images/ramdisk.image bs=1k count=4096 (cd fs_images;gzip -v9f ramdisk.image) every help would be appreciated... bye Andreas -- Life's not fair.
